Week #1

Published: 06/03/2019

What did I do this week? 

In continuing what I have done during the community bonding period, I was researching more about online algorithms for dimensionality reduction techniques. I've implemented the skeleton code for online Principal Component Analysis (PCA) using incremental algorithm and submitted as PR 

What is coming up next?

I'm currently trying to construct good test cases for PCA code. On the side, I have been writing code for parallel Non-negative matrix factorization (NNMF). I plan to submit PR for this soon as well. 

Did you get stuck anywhere?

At the moment, I'm very much stuck at constructing test cases. Since most online algorithms are approximations at best, some with nondeterministic output, it is quite hard to come up with a sound test case.
