Hi, The first part of the last few days of have been the most productive and the last part well not so much. 1. Fixing precompute for ElasticNetCV The function argument precompute=”auto” was being unused, in ElasticNetCV as mentioned in my previous post. Setting precompute equals auto uses a gram variant of the input matrix […]

Hi. It has been another slow week, and the heat and laziness at home (holiday season) isn’t quite helping. However I did manage to do a bit of work and this post will serve as a remainder for me to complete all the work that I have accumulated by the end of next week. 1. […]

Hi, the first week of (another) Google Summer of Code has ended, and I just realised that it is not going to be a joyride. Most of this week was spent in benchmarking, and trying to complete (?) this PR and so I did not write much code. However I learnt quite a bit in […]

My proposal, Improved Linear Models (http://goo.gl/NXicvU) has been selected for GSoC 2014 mentored by Alex and Jaidev. (A coincidence that my last GSoC proposal also started with Improved). Sklearn got 4 slots this time and all the best to my fellow students (Issam, Hamzeh and Maheshakya). Thanks to Alex, Gael, Vlad and other mentors for […]

Continuing from where we left last post, we were discussing the batch gradient algorithm. The iterative formula is The most obvious way to do this in normal Python would be to run a double nested loop, one from 1 to m to sum up the partial derivative term, and the other from 1 to n. […]

Hi, before I start writing anything, I would say sorry if this article (and the forthcoming articles hopefully) seems plagiarised. It mainly is from different sources, that I’ve written in my own words, mostly for my own reference, I would really love to see someone else benefit from this too, so here we go. Lets […]

Hi, I had taken this informal Stanford machine learning course last year, and since my GSoC finally got over I thought I would take it a bit more seriously. The Machine Learning course was in octave, and I started implementing a few algorithms using Python and Numpy. Here are a few must now concepts that […]
