I took this class a couple of years ago. It's outdated and overrated imho, with nowhere enough mathematical rigor to be useful. For example, the discussion of support vector machines (and classification in general if I recall correctly) was limited to two dimensions so that you didn't need linear algebra. The class also spends a lot of time on problems like path finding that you should be able to solve with your standard CS algorithms toolkit or just "logic" rather than needing to reach for anything that deserves the name "artificial intelligence" (at least today). Prof. Winston furthermore spends way too much time on vague truisms that may sum up or organize what's in his brain but aren't helpful to students. ("What if the answer doesn't depend on the data at all? Then you've got the trying to build a cake without flour.")

I hate to dismiss something as ambitious as this course and just tell people to blindly follow trends, but my honest advice would be to just skim these notes if you're interested and go take a normal machine learning course instead.

I have a side project to monitor the homepage of every domain and I want to detect the type of site - ecommerce, blog, forum etc. I've just started on it and ultimately I want to be able to automatically extract data, such as product information from ecommerce sites. Would these videos help here or is there anywhere else that someone would recommend. I know I sounds very naive here... and I am, but there might be som…

You could absolutely do it. Here's a few things you could do to get started (feel free to email me if you need more specific help, or have any additional questions- my email's in my profile): 1. Get as much data about each site as possible. Try to find data that you think will separate the non-ecommerce sites from the ecommerce sites. This data should be in a table form- think of an Excel spreadsheet, where each row…

This will be the hardest step. Feature extraction from html for identifying specific things like products, for any given site, is very hard (in my experience, which I will admit is pretty limited). Would love to be proven wrong though.

Professor Winston (the lecture in these videos), also teaches a higher-level, seminar based AI reading class called "The Human Intelligence Enterprise". It too, is an incredible class. Here's the schedule & linked papers from last semester: https://courses.csail.mit.edu/6.803/schedule.html (Disclaimer: Professor Winston is my current advisor)

Could you recommend any good books that would supplement this course? Also, why does this course seem so weird. What's with the "communication" assignments. Also, what's the deal with his project "genesis." Really interesting stuff. I hope I get a chance to pick your brain.

It depends on what you want out of it! If you're looking for immediately practical skills, of course you're better off taking 6.036 (machine learning). That's not the point of 6.034, which is something more vague that emphasizes intuition over rigor. Personally I think that offering both - a skills-oriented class and an idea-oriented class - is super cool and unique and I wish that pattern was more common.

> ultimately I want to be able to automatically extract data, such as product information from ecommerce sites A little OT, but although you could probably train models to figure that out, many (if not most) eCommerce sites should already be tagging their sites with semantic tags for product information, since it assists with indexing for search engines. Here, for example, is the Schema.org for a product ( https://sc…

That's really useful. Depends how many of the engines (Magento etc) use this - but I'll look into it. Thank you

Thank you. I'll check these out and also drop you a line

Minsky's Society of Mind would be a good launching off point. Other than that particularly famous example, I would just check out any of the authors of the papers in that link.

This class fulfills a communication requirement at MIT, so there are a one-page response/reflections due at each class. These reflections basically just ensure that you have a decent grasp at the main points of the paper, so that you would be ready for a seminar-style discussion in class.

Genesis is pretty interesting. Here's a link to the details: http://groups.csail.mit.edu/genesis/ But in short, it's an attempt to get computers to understand stories — and to discover what is the fundamental difference between the human mind and all other animals (spoiler alert: Winston's group believes it's the ability for humans to take two concepts and merge them into a new concept, indefinitely. AKA: creating "stories"). So the goal of Genesis is story-understanding.
