ml-103: Unsupervised learning and Recommender systems

January 23, 2014

Hello :) In the last 2 posts here and here, we got a general overview of what Machine learning is and also looked at a particular category ML algorithms, viz the "supervised learning" type.

Today we will briefly look at 2 more types of ML algorithms, viz the "unsupervised learning" and "recommender systems". I hope you remember that in the supervised learning types of ML algorithms, we get the "right answers" embedded in the training data. As against this, in the "unsupervised learning" algorithms, we do not get the right answers in the training data. In fact sometimes, there is no right answer at all, as I will show below.

ml-102: Supervised Learning

January 22, 2014

Hi! I hope you enjoyed the last post on introduction to ML. Today we will dig just a little bit deeper and understand the various types of ML algorithms. Although not complete, some of the different types of ML algorithms are:

  • Supervised learning
  • Unsupervised learning
  • Recommender systems

ml-101: Introduction to Machine Learning

January 21, 2014

Facts:

  • As some of my friends on twitter and facebook know, I recently completed the "Machine Learning" course on coursera, taught by "Andrew Ng" from Stanford university. I managed to get a 100% score on the programming assignments and the review tests (mean attempt of 2.22 on the tests), but did not get a completion certificate because I missed the "completion survey" before the deadline
  • While we teach, we learn. – Roman philosopher Seneca (see thisthis, this, and lots more)

Emacs: org-mode

January 20, 2014

Looks like I really have you hooked onto the concept of not only improving productivity, but changing the way you think by "killing the rat!" (see here, here, here and here for previous post on the "kill that rat" series). Good for both of us! For you because you will pave your way onto a completely different level, and for me because I am benefiting through this series too

  • improving my writing skills
  • writing/blogging improves cognitive skills (see here)
  • teaching is the best form of learning

Vimperator: part - 2

January 19, 2014

Hello there. Welcome back! I hope you have already read my first post on vimperator here, if not, I urge you to read that first and then come back here. Go on, I'll wait :)

Today I will show you some advanced, but even more awesome features of vimperator – the tool that takes web browsing to another level! The first is "modes". If you have used the fantastic vim editor before, you will know what I am talking about; and you will feel very much at home with vimperator (in fact, I am sure you would have guessed that the name "vimperator" stems from "vim"). For those of you who have not used vim, worry not; that is why I am here, to help you out :)
