One of my fond memories while growing up in Rawatbhata, a small town (and now a city!) of Rajasthan was birthday parties. These birthday parties used to be simple. We were all a bunch of similar-aged kids and would just invite each other for a mini celebration. Everything about …

The previous post formulated a solution for calculating spearman correlation on sparse matrices. The trick was simple - we exploited the sparsity structure in our matrix to prevent it from being converted to a dense form at any step. For spearman correlation, following this line…

An important property of the covariance function is that it is invariant under shifts, i.e., for any two random variables X\mathbf{X}X and Y\mathbf{Y}Y , you get the same covariance if you add constant quantitie to either $X$ or $Y$: Cov(X+a,Y+b)=Cov(X,Y) \begin{aligned} \text{C…

scvi-tools exists as a suite of tools for performing dimensionality reduction, data harmonization, and differential expression. One key advantage of using scvi-tools is that it inherently supports loading and training data in mini-batches and hence is practically infinitely scal…
