Authors: Teodora Baluta, Zheng Leong Chua, Kuldeep S. Meel and Prateek Saxena

1. The first paper focuses on efficient distance approximation in high dimension distributions. We propose an amazingly simple method that can compute L1 distance with rigorous guarantees. Come Poster Session 5 on Thursday.

Joint work with A. Bhattacharya, S. Gayen, and N.V. Vinodchandran

2. The second paper provides the first scalable method to test samplers in practice. Barbarik can now test samplers that sample from log-linear models. If you propose a sampling technique but can't prove its correctness, you can now use Barbarik to check its quality. Just the way we use testing for our software. (Poster)

Joint work with S. Chakraborty and Y. Pote

3. The third paper seeks to tame discrete integration with the boon of dimensionality (Yes, the boon not the curse). We extended our IJCAI-15's work of weighted to unweighted counting (thereby increasing the dimensionality) to handle rational weights. (Poster)

One of the reviews: “Rarely it is that there is a paper that proves a beautiful new theoretical result, explaining and simplifying previous work, and on top of that shows how it can be used to improve state-of-the-art practical algorithms. The paper “Sparse hashing for scalable approximate model counting: theory and practice” achieves exactly that.”
