Scikit-learn: Logistic Regression CV
Hi, It has been a long time since I had posted something on my blog. I had the opportunity to participate in the scikit-learn sprint recently, with the majority of the core-developers. The experience was awesome, but most of the time I had no idea what people were talking about, and I realised I have […]
GSoC update – Fixing precompute and LogReg CV
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 […]
GSoC 2nd week: Roadblocks and progress
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. […]
Machine Learning – Linear Regression (Part 2)
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. […]
Machine Learning – Linear Regression (Part 1)
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 […]
Machine Learning – A few basic concepts
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 […]
The end of a journey
It all began sometime during this February/March when I had nothing to do (I almost have nothing to do always) and people around me were doing cool stuff, when I thought of giving GSoC a shot. (I had initially thought GSoC was for people who knew ten programming languages before they were born, or who […]
Towards the end
Hi, I finally managed to do some amount of work for the past ten days, and I’m happy to day that all that I had wanted to do this GSoC has been pushed in and I’m waiting for comments on my final Pull Request. These were the changes that I had made. 1. Making stuff […]
Moving on to power series methods
Hi, Sorry for the late post this week. I couldn’t do much of work last week, but I did manage to write some code. First of all, I managed to get the lie group hint finally in. The Pull Request can be seen here, https://github.com/sympy/sympy/pull/2359 . Its nice to see the work that you have […]
Slow Progress
Hi, this week I decided to take a break from my actual GSoC project, and work on things that would indirectly some parts of my GSoC project. Firstly, I discovered this bug, when I was playing with the lie group solver, https://code.google.com/p/sympy/issues/detail?id=3976 . I thought I could fix it myself, but the source code of […]
