While going through Baby Rudin, I came across an interesting idea where Rudin constructs a function which is continous everywhere but differentiable nowhere. This was interesting. I tried to think of what could a function like this look like. The simplest function which is continuous but differentiable at a single…


In linear algebra, the determinant of a matrix is very nicely linked to areas and volumes. For example, the determinant of a 3x3 matrix is the volume of the parallelopiped enclosed by the three columns of the matrix represented as vectors in 3D- space. …

In genomics studies, understanding the various changes taking place in various signalling and driving molecules and pathways is crucial. To understand how various signalling processes are undergoing change or enrichment, statistical methods are employed extensively.

To give you some context, every cell in our body has various proteins which signal…


Characterising biological pathways from gene expression data

Gene Set Variation analysis is a technique for characterising pathways or signature summaries from a gene expression dataset. GSVA builds on top of Gene Set Enrichment analysis where a set of genes is characterised between two condition groups defined in the sample. GSEA (Gene set enrichment analysis) works on how…


Mongodb is a database which has it’s positives and negatives but regardless of what the world says knowing how to use it efficiently and to your advantage can save you time and effort and maybe switching to a different database itself(Postgres, anyone?).

Pymongo is the ORM (Object relational mapper) or…
