Multi-source conformal prediction: leveraging heterogeneity via localization
Rohan Hore, Anirban Chatterjee, Sayantan Choudhury
Many modern prediction tasks involve data from multiple heterogeneous sources, while the test distribution may differ substantially from any individual source. Although heterogenei…
Distribution-free inference on the number of changepoints
Rohan Hore, Aaditya Ramdas
Suppose we are given an ordered sequence of independent data whose distribution changes times at unknown locations, for some unknown . In this paper, we study the pro…
Local permutation tests for conditional independence: an adaptive binning perspective
David Chen, Rohan Hore, Rina Foygel Barber
In this work, we study the problem of testing conditional independence between random variables and given a confounder . The local permutation test (LPT) offers a princi…
Distribution-free root cause analysis
Rohan Hore, Aaditya Ramdas
We study distribution-free root cause analysis in multi-stream data, where an evolving underlying system is observed through multiple data streams that may each undergo distributio…
Online monotone density estimation and log-optimal calibration
Rohan Hore, Ruodu Wang, Aaditya Ramdas
We study the problem of online monotone density estimation, where density estimators must be constructed in a predictable manner from sequentially observed data. We propose two onl…
Conformal changepoint localization
Rohan Hore, Aaditya Ramdas
We study the problem of offline changepoint localization in a distribution-free setting. One observes a vector of data with a single changepoint, assuming that the data before and…
Distribution-free two-sample testing with blurred total variation distance
Rohan Hore, Rina Foygel Barber
Two-sample testing, where we aim to determine whether two distributions are equal or not equal based on samples from each one, is challenging if we cannot place assumptions on the…
