Understanding Axes of Difficulty For Long Context Tasks Via PredicateLongBench

Siddhartha Jain, Ameya Velingker

Large language models (LLMs) have demonstrated rapidly improving long-context capabilities, prompting a wave of benchmarks designed to evaluate them. However, existing long-context…

Even Sparser Graph Transformers

Hamed Shirzad, Honghao Lin, Balaji Venkatachalam +3

Graph Transformers excel in long-range dependency modeling, but generally require quadratic memory complexity in the number of nodes in an input graph, and hence have trouble scali…

A Theory for Compressibility of Graph Transformers for Transductive Learning

Hamed Shirzad, Honghao Lin, Ameya Velingker +3

Transductive tasks on graphs differ fundamentally from typical supervised machine learning tasks, as the independent and identically distributed (i.i.d.) assumption does not hold a…

Weisfeiler-Leman at the margin: When more expressivity matters

Billy J. Franks, Christopher Morris, Ameya Velingker +1

The Weisfeiler-Leman algorithm (-WL) is a well-studied heuristic for the graph isomorphism problem. Recently, the algorithm has played a prominent role in understanding the expr…

Locality-Aware Graph-Rewiring in GNNs

Federico Barbero, Ameya Velingker, Amin Saberi +2

Graph Neural Networks (GNNs) are popular models for machine learning on graphs that typically follow the message-passing paradigm, whereby the feature of a node is updated recursiv…

Fast -Approximation Algorithms for Binary Matrix Factorization

Ameya Velingker, Maximilian Vötsch, David P. Woodruff +1

We introduce efficient -approximation algorithms for the binary matrix factorization (BMF) problem, where the inputs are a matrix $\mathbf{A}\in\{0,1\}^{n\times d}…
