Free Machine Learning at Stanford

One of the cornerstones of the technology revolution, Stanford now offers some courses for free via distance learning. One of the more exciting courses is of course- machine learning

About The Course

This course provides a broad introduction to machine learning, datamining, and statistical pattern recognition. Topics include: (i) Supervised learning (parametric/non-parametric algorithms, support vector machines, kernels, neural networks). (ii) Unsupervised learning (clustering, dimensionality reduction, recommender systems, deep learning). (iii) Best practices in machine learning (bias/variance theory; innovation process in machine learning and AI). The course will also draw from numerous case studies and applications, so that you’ll also learn how to apply learning algorithms to building smart robots (perception, control), text understanding (web search, anti-spam), computer vision, medical informatics, audio, database mining, and other areas.

The Instructor

Professor Andrew Ng is Director of the Stanford Artificial Intelligence Lab, the main AI research organization at Stanford, with 20 professors and about 150 students/post docs. At Stanford, he teaches Machine Learning, which with a typical enrollment of 350 Stanford students, is among the most popular classes on campus. His research is primarily on machine learning, artificial intelligence, and robotics, and most universities doing robotics research now do so using a software platform (ROS) from his group.

 

  1. When does the class start?The class will start in January 2012 and will last approximately ten weeks.
  2. What is the format of the class?The class will consist of lecture videos, which are broken into small chunks, usually between eight and twelve minutes each. Some of these may contain integrated quiz questions. There will also be standalone quizzes that are not part of video lectures, and programming assignments.
  3. Will the text of the lectures be available?We hope to transcribe the lectures into text to make them more accessible for those not fluent in English. Stay tuned.
  4. Do I need to watch the lectures live?No. You can watch the lectures at your leisure.
  5. Can online students ask questions and/or contact the professor?Yes, but not directly There is a Q&A forum in which students rank questions and answers, so that the most important questions and the best answers bubble to the top. Teaching staff will monitor these forums, so that important questions not answered by other students can be addressed.
  6. Will other Stanford resources be available to online students?No.
  7. How much programming background is needed for the course?The course includes programming assignments and some programming background will be helpful.
  8. Do I need to buy a textbook for the course?No.
  9. How much does it cost to take the course?Nothing: it’s free!
  10. Will I get university credit for taking this course?No.Interested in learning machine learning-

Google Chrome introduces in-browser ads

Just saw a text ad on my chrome browser. Not a website just the browser.

No matter what website you go- well who has the browser can show you ads. I am glad the decade long stint of browsers as a sink hole for free stuff is going to go away soon.

Hmm.

Now if Microsoft comes up with in-Desktop Ads and slices the prices it would be fun.

Holiday season starts early!

 

 

UseR goes to Nashville, USA

So if Vanderbilt did lose (again) to UT (http://www.govolsxtra.com/news/2011/nov/20/video-tennessee-highlights-vanderbilt-game/) , they have somethign better to look before next season’s football season.

UseR is coming to Tennessee in 2012! This is the premier conference happens annually for R language (>2 mill users), and alternated between Europe and North America every other year.

Travel and Lodging Information

Vanderbilt University is located in Nashville, Tennessee, USA.

Air Travel

The nearest major airport to Vanderbilt University is the Nashville International Airport (BNA). The airport is about 10 miles east of the campus and downtown Nashville. The BNA website maintains a list of ground transportation options for air travelers. The approximate taxi fare from the airport to Vanderbilt University is $27. Shuttles and buses are also available from the airport. The latter is economical (approximate fare is $1.60), but the travel time is more than an hour.

Car Travel

Nashville is located at the intersection of three major interstates. Interstate 40 approaches from the east and west, interstate 24 from the northwest and southeast, and interstate 65 from the northeast and south.

Free online education by Stanford and MIT

One more reason American education is the best in the world- it has a big heart.

Stanford just announced free courses starting from Jan 2012- and they are online (so no visa blues) and free( as in speech and free as in beer) and just the same as actual courses (yes , the homework will have to be done, and the dog cannot eat the homework)

http://www.venture-class.org/

MIT meanwhile has 2000 courses  at http://ocw.mit.edu/courses/

 

– but I liked Stanford’s minimal , clutter free interface ( I read Steve Jobs biography- the interface hangover continues).

Hurrah for Stanford!

MIT needs to DESIGN  their free online courses website and maybe do more search engine optimization at

Research on Social Games

Social Gaming is slightly different from arcade gaming, and the heavy duty PSP3, XBox, Wii world of gaming.  Some observations on my research ( 😉 ) on social gaming across internet is as follows-

There are mostly 3 types of social games-

1) Quest- Build a town/area/farm to earn in game money or points

2) Fight- fight other people /players /pigs earn in game money or points

3) Puzzle- Stack up, make three of a kind, etc

Most successful social games are a crossover between the above three kinds of social games (so build and fight, or fight and puzzle etc)

In addition most social games have some in game incentives that are peculiar to social networks only. In game incentives are mostly in game cash to build, energy to fight others, or shortcuts in puzzle games. These social gaming incentives are-

1) Some incentive to log in daily/regularly/visit game site more often

2) Some incentive to invite other players on the social network

A characteristic of this domain is blatant me-too, copying and ripping creative ideas (but not the creative itself)  from other social games. In general the successful game which is the early leader gets most of the players but other game studios can and do build up substantial long tail network of players by copying games. Thus there are a huge variety of games.

However there are massive hits like Farmville and Angry Birds, that prove that a single social game well executed can be very valuable and profitable to both itself as well as the primary social network hosting it.

Accordingly the leading game studios are Zynga, Electronic Arts and (yes) Microsoft while Google has been mostly a investor in these.

A good website for studying data about social games is http://www.appdata.com/ while a sister website for studying developments is  http://www.insidesocialgames.com/

As you can see below Appdata is a formidable data gatherer here (though I find the top App – Static HTML as both puzzling and a sign of un corrected automated data gathering),

but I expect more competition in this very lucrative segment.
