Quantifying and Reducing Bias in Maximum Likelihood Estimation of Structured Anomalies

Uthsav Chitra, Kimberly Ding, Jasper C. H. Lee +1

Anomaly estimation, or the problem of finding a subset of a dataset that differs from the rest of the dataset, is a classic problem in machine learning and data mining. In both the…

Random Walks on Hypergraphs with Edge-Dependent Vertex Weights

Uthsav Chitra, Benjamin J Raphael

Hypergraphs are used in machine learning to model higher-order relationships in data. While spectral methods for graphs are well-established, spectral theory for hypergraphs remain…

A Weighted Exact Test for Mutually Exclusive Mutations in Cancer

Mark D. M. Leiserson, Matthew A. Reyna, Benjamin J. Raphael

The somatic mutations in the pathways that drive cancer development tend to be mutually exclusive across tumors, providing a signal for distinguishing driver mutations from a large…
