Stanford to host more online classes (cs101-class.org)
493 points by ivoflipse 1546 days ago | past | web | 116 comments



I get easily excited about education-related topics so I may be over-reacting, but I think these classes will jump-start an educational revolution, and that people will start to fully appreciate just how inefficient traditional teaching methods are.

Some people like to say that this is nothing new because video lectures were posted on the internet for several years now (for example MIT Open Courseware etc.), but I think this misses the point entirely. There is a huge difference between low-quality video/audio recording of a prof mumbling for an hour and post-processed, perfected snippets of videos presented in a coherent fashion, and most importantly with supplementary materials that encourage people to actually apply their knowledge and get feedback. In addition, the fact that many people take the class at the same time also enhances the experience for everyone, and we've seen study groups form everywhere around internet.

Full disclosure, by the way, I'm a CS PhD student at Stanford and I am a (voluntary) co-creator of the programming assignments for the current ML class. It is a lot of work, but the way I see it, we only have to put great assignments together a single time, and thousands of people can enjoy them and benefit from them for years and years to come. That is what I call time well spent.

I hope all these classes go well, and I'm looking forward to telling my kids about what education used to be like in the old days. I have a feeling that they'll find it hard to believe me.

As a consumer of Stanford's online classes(though not the ML class. I'm waiting for the CS 229 - vs the CS 229A - version), let me take the opportunity to thank you. Your efforts are totally appreciated. You are right, this is revolutionary. Glad to see that Stanford is keeping up (and building!) momentum rather than this being a one off effort.

-----


thanks, I should add (and I hope this is somewhat obvious) that there is a team of about 7 or 8 of us in total. A lot of work goes into site/technical/video processing etc, and then there are 2.5 of us making the assignments.

The real hero behind the assignments is Jiquan Ngiam (http://cs.stanford.edu/~jngiam/) who is in charge and does most of the work. He is awesome, brilliant, very hard working, and I thoroughly enjoy hacking with him on the ML class until late AM.

-----


Me and my wife have been following Professor Ng's ML class and one of the highest points for us has been working through and trying to understand the programming exercices.

Our personal thanks to you and the other "1.5 people" working on that. ;)

Cheers!

-----


Thanks for that. I suspect Prof Ng will get a lot of praise for the class but I suspect some of it is intended for the people behind the scenes (not always easy to find out who they are).

-----


I'm super excited about this, thanks so much for taking the time, it's appreciated by those who missed the opportunity to get a CS degree.

-----


Thanks to all you guys! The programming assignments are brilliant. All my (non-technical) friends and family I've been telling about the class think the whole thing sounds really cool.

-----


Really great stuff. Thank you and your team for your time and efforts on this. I learned a lot already from the ML class and can't wait to take the HCI class.

-----


The ml-class programming exercises are excellent. Thanks.

-----


The homework and in-video questions are what keep me involved. I have such a busy schedule that its difficult to maintain the discipline to simply keep up if there were only videos. However, having external deadlines and practical things have encouraged me to make the time (and I'm very happy about it).

I agree that this is potentially revolutionary. Before these courses, I couldn't have imagined doing a 'distance-learning' course. I suspect there are many other folks that feel the same.

Also, thank you for your work on the ML programming exercises! I've found them fantastic in getting my head around how to practically 'encode' the things from the videos. Much appreciated.

-----


The time management part is difficult. I tried to keep up with ML but because I kept thinking, I'll do it over the weekend, I got a couple of weeks behind and ended up dropping. I'd love to join a study group in conjunction with the class - then I have the social pressure to keep up (but not necessarily share grades..)

-----


I think independent study groups are the big win from this. This isn't the first time high quality videos have been online (the full "regular" ML class can be viewed on youtube), but because it's more "real-time" it allows for groups of people to work through the material together. It would be significantly more difficult to co-ordinate that with the MIT videos that you can watch whenever you'd like.

Both are great resources, and I don't know that the Stanford classes will be able to sustain their ability to get people to create their own study groups. Our study group here in Cleveland Ohio gets 5 - 10 people each week, but we're drawing from areas almost an hour away. Future ML and AI classes will have a tougher time having that same draw, as those most interested will have already gone through the material and would be much less likely to drive an hour each week for a study group.

Survey classes like the ML and AI class work very well with this format. I'm looking forward to seeing how it fits with more specific classes. There are times in the AI class that are a bit "hand-wavy", which is OK for an over-view/survey class. I'd find that a bit more annoying on something like the upcoming natural language processing class.

-----


"Future ML and AI classes will have a tougher time having that same draw"

Really? Or are you pioneers? I know reading your comment just greatly increased the probability that I will take another class (currently in db-class) and seek out a study group next time.

-----


I'm a big fan of the study group setting for these classes. It's been a great way to find and work with like-minded people. I'd encourage you to find one for future classes, but I'm not sure how sustainable they are.

The AI and ML classes drew a lot of attention to start with (over 100k signups). Follow up or repeat classes will obviously draw less interest. I'm interested in seeing how that translates to viable study group sizes. The good news is that the minimum viable size of a study group is fairly small.

-----


thanks, I agree with you-- there is something psychologically interesting about it that I can't quite understand, but it certainly seems like this format better maintains student motivation. It's a step in the right direction at least... just the first iteration of a gradient descent ahead of us ;)

Also, good point about the programming exercises. Especially with topics like this I think it is easy to fall into trap of thinking you "got it" if you just watch the videos. Programming exercises force you to think it through on a whole different level and, I think, lead to better understanding and retention.

Anyway, great, I hope you stick with the class!

-----


> there is something psychologically interesting about it that I can't quite understand

I swear, it's an extra pleasure hearing a song I like on the radio (over just playing it myself), knowing that a lot of other people are listening to it too. Maybe that's a new form of 'social computing' to be exploited :).

-----


I've been watching Susskind's physics lectures on youtube, which are also from Stanford (continuing education). They're just video of the lectures, no homework or quizzes.

They're great stuff and he's really gotten me to understand a lot of the "why" of physics rather than just the "how".

Having said that, I'd love to have homework along with them, even just suggested problems with an answer key.

-----


I have a masters in CS, and I am taking the online ML class. I highly appreciate how well organized the class is. Thankyou.

I have a question though, is there a way these classes can be made to be taken anytime a student wants?

The problem I am facing is that since I am also working fulltime, I just in time manage to submit the homework, and as a result, I can not take more than one classes at the same time, like the DB and AI classes in this case.

-----


We'll have to see what happens to the evaluation systems once the term ends, but at the very least you can sign up for all the classes and download the videos.

More importantly, for evaluation purposes, the quizzes and exercises can be submitted late, though penalized in points. Since what you get out of the course for having a high score (a certificate/letter of completion?) is worth about as much as toilet paper, you can still do the exercises and be evaluated on them even weeks later. We'll have to see if they keep the system running past the end of the semester - probably won't happen with ML, but maybe DB will stick around a bit.

AI, well, that doesn't have any homework.

So, next semester, sign up for all the courses, stick with all of them past the introduction week, pick one or you you'll focus on, and dabble in the rest.

Well, maybe not the CS101 course...

-----


If you don't need concurrent learning to be motivated you can watch videos later. I wish there would be a way to be evaluated without any after-deadline penalty.

-----


I'm taking the ml class right now, thank you! Everything you say is absolutely true, enrolling in this class vs watching some videos is like night and day: - a large number of other students who are at the same cohort helping each other - lecture materials - programming assignments - comprehension questions

I don't feel quite like I am taking a real masters level computer science class mainly because the assignments are easier (you guys set up a lot of the boiler plate for us and we implement a few core algorithms). That said, the assignments have been a big part of me retaining the concepts and since they are not ball breakers, I can actually keep up with 30-60 minutes a day, with perhaps a couple hours one day on the weekend.

Professor NG is also an amazing teacher. I'm cautiously optimistic that the other teachers will be as good.

-----


I definitely agree with you on the "huge difference between low-quality video/audio recording of a prof mumbling for an hour and post-processed, perfected snippets of videos presented in a coherent fashion, and most importantly with supplementary materials that encourage people to actually apply their knowledge and get feedback" part.

I started the site noexcuselist.com as a page to direct people to the best places to learn on the web. In doing so, I had to go through tons of web pages claiming that they taught things for free. The sites that I was really excited for like the Open Courseware sites were a bit of a disappointment for me. It'd be pretty hard for someone to learn a entire topic using it due to the incomplete lectures, some classes that weren't available, and the lack of lecture notes and homework that went with it.

I'm pretty excited to see the development of this one that you're working on though. Good luck and keep us posted!

-----


Your webpage is nice. Thank you for sharing!

-----


Thanks for your work, the course looks very impressive. Probably the best introduction into the basics of ML I've seen.

By the way, will http://jan2012.ml-class.org/ be the same as the current ml-class? I mean is it the same course, or a more advanced one?

-----


They say it will be the same class as current at ml-class Q&A - http://www.ml-class.org/course/qna/view?id=3925

-----


Jason Kuen Wen Yong's comment mentions (and I concur) that there are additional topics in the Jan 2012 course than the current one like deep learning. Any clarification on this?

-----


Ah, nevermind, just read mlclass twitter

-----


I'm taking the ML class right now, so I want to thank you for taking the time to work on the programming assignments.

I was very impressed with the quality and especially how easy it is to submit them.

-----


Seconded. For someone who is being newly introduced to ML concepts, applying them right away can be daunting. The exercises do just enough hand-holding to make sure they don't get lost, but give enough leeway so that they know what kind of mistakes they are making.

And the submission process is just mind-numbingly simple (which is good!).

-----


I largely agree with you, but, I feel that the in class presentations, when recorded well, are more engaging.

Personal opinion being what it is for me I find it far easier to listen to Professor Sahami's recorded lessons (CS 106A) for an hour than I do Prof. Widom's into to DB classes. This is not intended as a slight to any person at Stanford. The real difference comes down to watching someone engage an audience and some one speaking to a camera.

Strictly my opinion based on a very small sample pool.

-----


I second this, I am in the db-class and I can't help but think it would be more fun with an interactive class. Widom is a great teacher, but it's weird to just watch her in that room by herself talking about database stuff.

-----


I'm taking the ML class and I love it! I agree with everything you said above, and I'd love to see a more advance ML class in the future. Keep up the good work!

-----


Thank you very much for your efforts, I've been enjoying ML class so much. The only thing I disagree with, is that the courses are time-bound. I have a day time job, and I'm only able to take 1 course. However I don't see any reasons why you shouldn't allow people getting through the courses outside of the time frame. This would be more convenient for a good part of the target audience, because it's the people who actually don't have enough time to enroll in the real university course.

-----


Agreed.

E-learning has the potential to: decrease the costs of getting an education, create the potential for "mass customization" of education, reduce credentialism in society, make learning an end in itself for many people, force universities to become less complacent, and probably many other effects I am overlooking right now.

Starting an e-learning startup is something I REALLY want to do. I love learning and I love startups.

I hope I can make that happen someday (nudges everyone with similar dreams).

-----


Karpathy: Do you know if prof. Ng will cover the issue of sparse data in his lectures?

When the number of dimensions is much greater than the number of samples and most of your cells in a matrix are equal to zero then most of the ML algorithms don't behave too well. It's very common problem in NLP to have sparse matrices.

-----


it seems there will be a specific class on NLP: http://www.nlp-class.org/

-----


Thanks for the great exercises, you made them really fun! I think the course is absolutely stellar.

-----


Any chance (some of) the code for the platform could be shared? I particularly love the exercises (review questions) and the way some questions are embedded in the videos. Thank you and your teammates for some great work.

-----


Thank you. There is attention to detail here. It actually amused me when I watched Andrew Ng's videos at 1.2 or 1.5 speed that his voice didn't become squeaky because it is frequency modulated.

-----


Thank you for your work. I am in both the AI and the ML classes, and having some work that we actually do stuff, is a great learning aid and I wish the AI course had something similar too.

-----


Just want to say "Thank you!" for all the hard work you and your colleagues put into ML class. This is the best learning experience I've had in my entire life.

-----


thank you for your greate work. Without you help, here we in China can't get access to those wonderful education resources.

-----


Thank you so much, you guys are awesome..really well organized unlike aiclass

No mention of the two Entrepreneurship classes? Were they not there originally?

Technology Entrepreneurship: http://www.startup-class.org/

Learn Launchpad: http://www.launchpad-class.org/

--------------------

So what are these courses? Video isn't working for me at the moment but judging by the descriptions they seem to be more involved than the CS courses:

Quoting from the Launchpad description:

  Instead you will be getting your hands dirty talking to
  customers, partners, competitors, as you encounter the 
  chaos and uncertainty of how a startup actually works.
EDIT: 10 minutes later, the Technology Entrepreneurship class redirects to a blank page and is no longer linked to from the other courses...

Hey, think this means there might be even more courses coming out later?

-----


Interesting that the SaaS class is being done by two Berkeley profs (and is the only one missing the Stanford logo).

-----


I think it's great. Hopefully this idea will catch on with other universities; one day we might see an entire Khan Academy type site for computer science classes taught by the worlds leading experts.

-----


I presume that glaring .com for the AI class is another indicator that the AI class will be a for profit operation at some point.

-----


Since there seems to be someone involved in running these classes in this thread, I just want to throw this out there. The higher ratio of quizes per minutes of lecture the better.

I think its ideal to never go more than 2-3 minutes without asking us something, even if its trivial.

Right now I'm taking the AI classes, some of the units follow this rule and keep us paying attention through what I imagine would otherwise be some pretty dense stuff.

A few of the units (looking at you Professor Norvig) have had stretches 15+ minutes of lecture without asking us anything, just going to say, retention from those stretches was low.

Personally I really like it when they quiz our intuition of a subject before they lecture it, though it seems like other people complain about that on the reddit forum

-----


I would say that forcing longer time spans before quizzes forces you to maintain your attention and thus would help you retain your learning for longer.

-----


I'd guess otherwise, but that would be easy to test for the course organizers.

-----


I, for one, am really hoping this is a start of a trend - where coursework, even if just in a prerecorded format, is available to all, with the tuition going towards the rich in-person experience and grading/certification for the student, much like the way the primary tech conferences have been trending for free content for al.

-----


MIT OCW requires a far higher level of intrinsic motivation. Stanford has almost nailed it. While online learning has taken Space out of the equation, Time, it seems, is still a big variable. Having people do the course at the same time with deadlines is working. They just need to work through the technical glitches, which shouldn't be that hard.

-----


FYI: the "CS-101" course is a really really basic introduction to computational thinking. If you want intro programming you probably want CS106A, which hasn't been put into this format yet.

101 is taught by Nick Parlante, though, who was one of my favorite profs at Stanford.

-----


This is fantastic. I would also like to do some course in mathematics (under graduate level calculus, discrete mathematics ) to improve my skills. Are there any good places/resources where I can learn these things (video lectures with quizzes in between will be a nice choice). I am also ready to take a paid certified course if some reputed college is offering them online.

-----


Maths is certainly not my strong point, but you should check out khanacademy.org. There might be some videos there.

-----


Go to the Aiclass website. The have links to khanacadamy videos that one needs to know.

-----


This is fantastic. A few weeks ago Sebastian tweeted about the possibility of having an online Master's when they met with the president of Stanford. Has anyone heard anything new about it?

-----


Although I had to drop the previous classes due to time, this looks promising. Particularly with the unified style; that is the one thing that seemed to hurt this years effort - The most widely advertised course (AI) had the worst layout and 'features'.

-----


Both ML and DB classes are better executed than AI class. AI class is backed with a broken platform by a small startup, whereas ML class was run by code developed in Stanford. AI class also had jarring video editing which totally broke the rhythm. Both ML class and e.g. Khan Academy has this natural flow that is pleasure to follow.

To me it has been surprising how big difference in experience the technical execution between classes made. Both Norvig and Thrun are clearly good teachers, but AI class failed because of the poor technical implementation.

-----


I'm doing ai-class and I find it just fine. After the first two weeks, all the technology worked just fine - what problems are you referring to?

The video editing is also fine. If such minor issues break your rhythm, you might need to rethink your approach to the lessons.

Given that there are still thousands of students in the class and enjoying it, it didn't "fail" at all.

-----


The video editing is also fine. If such minor issues break your rhythm, you might need to rethink your approach to the lessons.

Video editing in AI class is against the knowledge that we have learned in 100+ years of movie editing. Cutting 1-2 seconds but keeping the same scene gives a jarring experience.

They cut out a few seconds so that you don't need to watch Norvig or Thrun to finish writing of a word or sentence, but that's saving time in the wrong place in my opinion. If you watch Khan Academy or ML class, those 1-2 seconds give a natural pause, that you can use to think about the subject.

I've nothing against the pen and paper approach, although occlusion is sometimes a problem. Based on my experience with Khan, AI and ML classes drawing by hand is the essential thing, is it less important if it's done electronically or by pen and paper.

Anyway, my main point is that execution of e.g. Khan Academy and ML class are better than AI class, and I'd personally prefer that inspiration for new online education courses is taken from them instead of AI class approach.

-----


They work, but they're less usable than the db and ml counterparts.

On the other hand, the videos themselves are actually better (I love the pen-and-paper approach), and there's a lot more small questions within lectures, which helps keeping my ADD in check.

-----


Try watching the ML or DB lectures in '1.5x' mode (it speeds the video up). Because of the faster pace, it is a really good counter to my ADD tendencies. Also it is really nice when you are trying to cram a few lectures into a short time period.

-----


I quit early because the platform was unusable (slow, buggy)

-----


I wouldn't call the ai-class.org platform broken. It's just not done yet.

The AI class is like a beta test and there are plenty of bugs and problems. The content is still good, but the programming problems and automated grader that would be necessary for students to really absorb the advanced material doesn't seem to be on their radar. The result is a certain superficiality.

The ML class is much more developed. In the first few weeks the contrast of the finished, professional seeming ML class with the rough and hacky AI class was extreme but AI is catching up.

I'm looking forward to improvements in both platforms and new material in the spring. Other competitors like Kahnacademy are exciting, too.

I'd like to see more study groups around the world building this into a movement with broadening impact. Neither class had direct support for forming study groups. If you have to go on Reddit to get together with people, you're excluding 50-90% of the people who would use a simple no-friction geo-aware meetup-style tool if it were on the site's front page and main menu. Since study groups have a minimum size threshold to remain viable, that eliminates a magnified portion of potential participants.

So I'm pleased and still hope that this could be a mass-movement that leverages technology to change the way education is done around the world. Competing platforms is a better bet than one great platform for perfecting hard to build but needed features like labs, programming assignments, study group support, office hours and teachers' assistants, and homework help and hints.

The future, at least in our industry, is bright.

-----


Spot on :) I'm currently taking both the ML and AI classes and the difference is disturbing.

I'm sure things will improve in the next iteration, though, and after all I'm very grateful that all these courses are publicly available for free.

-----


What kind of time commitment does it require?

-----


I started out spending closer to 10 hours a week earlier on in the AI course. We initially had a local meetup and I spent more time reading the textbook for the first few units. Had to scale it back to 5 or so hours, which is good enough to get through it, but not enough to spend extra time discussing with others, reading supplementary materials, and coding.

-----


For me it took 3 or 4 hours a week per course. It doesn't sound like much, but pre-arranged plans made it hard to find a decent sized piece of time (>1 hr) in which to do the work.

-----


Thanks. This is the critical nugget of information missing from the course information pages (unless I'm just lacking in observation skills).

-----


For me it was maybe 5-6 hours per week (for AI course).

It was quite intensive thinking, though, really requiring concentration and effort; the courses themselves (ie just video) were maybe about 1 hour per unit, and there were two units per week.

-----


I've put about 2-4 hours a week into the ML class. However, I know that math (basic linear algebra and calculus so far) and have done scientific computing before so I can churn the exercises out pretty quick. The exercises are the best part. It's nice having a set of problems to work on instead of just watching an hours worth of videos each week.

-----


Will the materials for these courses (videos + ref material + assignments + solutions) be available for browsing after the course has ended?

-----


For the ongoing courses it will be available, so I guess it will be the same for these also.The thing you miss out on taking them later is the structure of the class with deadlines (very good incentive to really sit down and learn!) and personal letter from the teachers

-----


Do you have a reference for that about the ongoing courses? I tried to find something about it a while ago and couldn't. It would be awesome if they plan to just leave the whole web app with quizzes etc up and open for people to use at their own pace.

-----


From The DB class FAQ:

Q: Will the materials still be available after the course is over?

At the very least, all of the materials in the OpenClassroom repository will be available, including videos with embedded quizzes, lecture notes, course materials, software guides, and extensive do-it-yourself exercises with solutions.

http://openclassroom.stanford.edu/MainFolder/CoursePage.php?...

-----


I was actually wondering about the AI class... it's not listed on the Open Classroom site. It's really weird that they are not under the same umbrella but I guess the AI class is managed by that start up or something? Thanks anyway.

-----


Copy pasting like a madman here, sorry about that.

From AI class FAQ;

Will the videos be available without enrolling? Yes, however you will not have access to any other features of the course including homeworks, exams, discussion groups, and posts from the professors.

So I guess you're out of luck as far as the web app, quizzez etc. All the videos are on Youtube so they will be available after the class has finished

-----


That question doesn't specifically address what happens after the course is over. I'd read all of this before, and that's why I was asking for a reference. Oh well, thanks again.

-----


The SaaS class (http://www.saas-class.org/) is missing in the title. Looks exciting!

-----


For me, as a brazilian computer engineering student, I think these classes are amazing. Although I study in one of the best computer schools in brazil ( www.cin.ufpe.br), my classes tend to be bad and boring. My teachers have Phd's and all those letters, but cant teach in a good and engaging way. And my classes have old subjects, because they made the curriculum 10 years ago.

Thank you so much, Stanford, the teachers for the modern and brave choice to teach people all around the world, thanks for all the students engaged in making the classes available for everybody. and thanks hn buddies for always giving the good news.

Will enroll to SaaS and hci or nlp.

-----


Arghhhh. I find these incredibly frustrating. I am writing a senior honors thesis for my university, and wanted to take as few classes as possible this year to focus on my thesis work. The ML class has distracted me this semester, and it looks like things are going to get worse next semester.

On a serious note, does anyone know if there are plans to continue these courses next year? I suppose it will really depend on how well each class goes, but I mostly feel pressured to take these because I'm afraid I'll miss them.

-----


This is very exciting news, very much an autodidact's dream.

I've been enjoying crawling my way through the great ML classes by Prof Andrew Ng, and had been wondering if by any luck other classes would be provided for future semesters. Seeing this just makes me really happy, and thankful to Stanford. Not only is it the future of education but also gives countless people around the globe a chance to learn topics they may otherwise have never had access to (I am one in this category).

Signing up for NLP!

-----


Anyone know if AI-Class will be running again in 2012? The links between the 2012 courses suggest not, but that could just be down to Ai-Class being different.

-----


My guess is AI and DB class will be running again in the fall of 2012. They will probably follow the schedule Stanford has on these courses. Just a guess though

-----


+1

also, what about the DB class ? will it be running again in 2012 ?

I couldn't "attend" more than one at the same time (especially the advanced tracks) and I already joined the ML class.

-----


Prof. Widom said that if she were to run the class again, it would be at the same time next year, because thats when she runs it at Stanford.

-----


Does anyone else think a startup could be built around a software platform that universities could use for releasing their content to the world?

See here: http://ideashower.posterous.com/idea-platform-that-universit...

If anyone wants to work on this, contact me :)

-----


Unfortunately, Blackboards' patents preclude this from becoming a reality. For the next 15 years, Blackboard has an exclusive right to practice this "virtual classroom" business method.[1]

Their patent pledge[2] promises that they will not assert their rights against any open-source or home-grown initiative, which is why Stanford et al. are able to get away with hosting their own content in this format.

It's a harsh reality that by itself makes the case for patent reform.

-----


You mean they can just sit on the general idea of virtual classrooms? What a bunch of dicks!

-----


Welcome to why patents suck.

-----


You should contact Thrun and Norvig who are running ai-class, they've started http://www.knowit.com/

-----


Yeah but I would have to convince them that they need some random dude in Sweden :)

-----


Does anyone know when Tim Roughgarden's class will be available? Data structures and algorithms?

-----


If you're talking about his undergrad class (CS 161), there are at least videos of his lectures on OpenClassroom: http://openclassroom.stanford.edu/MainFolder/CoursePage.php?...

The lectures are broken up into segments (which you might find convenient or annoying). There's not much more than that, unfortunately. If you want exercises, his problem sets are mostly from Kleinberg & Tardos, sometimes with problems from CLRS.

-----


One of the great hidden benefits of those classes is to taste the flavor of the classes, should they want to apply to the university. I would particularly interested in the difference between Berkeley classes (SaaS) and Stanford classes (CS101 or ML)

-----


Now I know what am I doing next spring. :D Sweet!

Thanks for everyone at Stanford working on this and making it possible. What an amazing collaboration between teachers and students (as the current ML, DB and AI classes show as well).

-----


I'm taking the ML class right now and it is truly excellent - all aspects of it, the videos, material and assignments. Can't recommend these enough.

The only problem with the winter classes is I can't decide which to take!

-----


Join all the ones you're interested in then drop the least interesting classes. I joined the ML and AI class this year then focused on the ML class because the octave exercises are a great way to learn.

The probabilistic graphical models looks like it may have a similar format as the introductory video mentions automatically graded programming exercises.

-----


I have a feeling they'll all be copying the format/software of the ML class, at least based on the introductory videos.

-----


That would be great. I was disappointed when the AI class didn't have programming exercises. I feel like these were the part that really enforced the learning for me.

I think another part that worked well was that getting 100% for each exercise is readily achievable. I want to finish each exercise perfectly so I don't break my 100% record for the course. I think this works well for motivation.

_Yesssss!_ I was really hoping for NLP!

Do you get an email confirmation on signing up? Also how does this course work? The site didn't provide any information about that ― although I haven't seen the 'about course' video.

Has anybody here tried this before? Are the videos webcasts or pre-recorded video that I can download/view at anytime?

Also is it open for everybody or will the sign ups be restricted?

All in all this looks awesome and I'm very much interested in the Game Theory and SaaS classes! :)

Having done the db-class here's my experience of how things worked. Although I understand it's different from class to class.

Course is like a typical Uni course. Lectures, readings, tests and exams.

I received an email a week before the class started.

Videos came out and could be watched in the browser or downloaded.

Open to anyone.

-----


All of these courses look so appealing, I want to do ALL OF THEM (except maybe CS101).

-----


I wish they would add a course on Probability or Probability and Statistics.

-----


I highly recommend http://khanacademy.org for Probability.

http://www.khanacademy.org/#probability

I went through all the videos on that subject in preparation for AI Class and it helped me tremendously.

-----


I was wondering if taking these courses improve your resume in a general way and/or help your chances to get into a good graduate school program.

Can someone please explain a little about HCI? For example, how it applies to real world, types of things you learn in class etc.

-----


As it names suggests, HCI is a field that attempts to understand the way we interact with machines. The idea is that by understanding this relationship we should be able to build better designed software/hardware (or more usable, as it's known in the field). It's a merging field involving mainly psychology, design and computer science. As for how it applies to the real world, either UX design or usability engineering are probably the most commonly found examples out there.

-----


I think it is about making a good design of your product.

-----


So, you people have a lot of friends right now (including me). Care to make a wish from the internet to give something back? :)

-----


Did anyone check this link too on that page www.entrepreneur-class.org. I think it's going to be useful for startup guys

-----


This is awesome! I'm scheduling my spring classes around these classes.

-----


Nick Parlante is a GREAT instructor!
