Non-negative matrix factorization algorithms generally improve topic model fits
Peter Carbonetto, Abhishek Sarkar, Zihao Wang +1
In an effort to develop topic modeling methods that can be quickly applied to large data sets, we revisit the problem of maximum-likelihood estimation in topic models. It is known,…

Lie algebroids, quantum Poisson algebroids, and Lie algebroid connections
Satyendra Kumar Mishra, Abhishek Sarkar
In this paper, we consider Lie algebroids over commutative ringed spaces. Lie algebroids over ringed spaces unify the existing notion of Lie algebroids over smooth manifolds, compl…

-Lie Algebroids over Topological Ringed Spaces
Mainak Poddar, Abhishek Sarkar
Lie algebroids over a topological ringed space provides a unified framework to study various geometric structures. This geometric concept is intimately connected with well-known al…
