A provable SVD-based algorithm for learning topics in dominant admixture corpus
Trapit Bansal, Chiranjib Bhattacharyya, Ravindran Kannan
Topic models, such as Latent Dirichlet Allocation (LDA), posit that documents are drawn from admixtures of distributions over words, known as topics. The inference problem of recov…
Temporally Coherent Bayesian Models for Entity Discovery in Videos by Tracklet Clustering
Adway Mitra, Soma Biswas, Chiranjib Bhattacharyya
A video can be represented as a sequence of tracklets, each spanning 10-20 frames, and associated with one entity (eg. a person). The task of \emph{Entity Discovery} in videos can…
Dynamic Multi-Relational Chinese Restaurant Process for Analyzing Influences on Users in Social Media
Himabindu Lakkaraju, Indrajit Bhattacharya, Chiranjib Bhattacharyya
We study the problem of analyzing influence of various factors affecting individual messages posted in social media. The problem is challenging because of various types of influenc…
Randomized Algorithms for Large scale SVMs
Vinay Jethava, Krishnan Suresh, Chiranjib Bhattacharyya +1
We propose a randomized algorithm for training Support vector machines(SVMs) on large datasets. By using ideas from Random projections we show that the combinatorial dimension of S…
