Using Geographic Location-based Public Health Features in Survival Analysis
Navid Seidi, Ardhendu Tripathy, Sajal K. Das
Time elapsed till an event of interest is often modeled using the survival analysis methodology, which estimates a survival score based on the input features. There is a resurgence…
Nearest Neighbor Search Under Uncertainty
Blake Mason, Ardhendu Tripathy, Robert Nowak
Nearest Neighbor Search (NNS) is a central task in knowledge representation, learning, and reasoning. There is vast literature on efficient algorithms for constructing data structu…
Optimal Confidence Regions for the Multinomial Parameter
Matthew L. Malloy, Ardhendu Tripathy, Robert D. Nowak
Construction of tight confidence regions and intervals is central to statistical inference and decision making. This paper develops new theory showing minimum average volume confid…
MaxGap Bandit: Adaptive Algorithms for Approximate Ranking
Sumeet Katariya, Ardhendu Tripathy, Robert Nowak
This paper studies the problem of adaptively sampling from K distributions (arms) in order to identify the largest gap between any two adjacent means. We call this the MaxGap-bandi…
Learning Nearest Neighbor Graphs from Noisy Distance Samples
Blake Mason, Ardhendu Tripathy, Robert Nowak
We consider the problem of learning the nearest neighbor graph of a dataset of n items. The metric is unknown, but we can query an oracle to obtain a noisy estimate of the distance…
Zero-error Function Computation on a Directed Acyclic Network
Ardhendu Tripathy, Aditya Ramamoorthy
We study the rate region of variable-length source-network codes that are used to compute a function of messages observed over a network. The particular network considered here is…
