Random thoughts

Its nice to see the following:

$$9.1\times{9.1} + 9.1 = 91.91$$

I pondered a bit more and it turns out be of the following pattern

$$99.1\times{99.1} + 99.1 = 9919.91$$
$$999.1\times{999.1} + 999.1 = 999199.91$$
$$9999 …

Often we run into issues of generating high-resolution figures for publication, and, it is a bit of pain. Let me explain a couple of points which made me write this post.

  • Seaborn (sns) is an awesome tool to do the plotting
  • Matplotlib is needed to do nitty-gritty changes in Seaborn …

Bayesian inference to L2-regularized MLR

Posted on Fri 09 March 2018 in Concepts

I was really happy to read the chapter 1 of Bishop's Pattern Recognition book and realize the relationship between L2-regularized MLR and Bayesian perspective. On page 30, he shows that if weights follow a gaussian distribution conditioned on selected hyper-parameter, then the maximum likelihood would take the following form:

$$ \frac …

CpG/DNA methylation

CpG methylation

CpG methylation is an epigenetic modification on DNA. At the molecular level, CpG methylation involves the addition of a methyl (CH3) group on the C5 atom of cytosine, yeilding 5-methylcytosine (5mC). Although the change is very small, but cumulative effect is profound, for example X-chromosome inactivation. Recent …
