Conference Advances in Neural Information Processing Systems · January 1, 2024 We study distributed goodness-of-fit testing for discrete distribution under bandwidth and differential privacy constraints. Information constraint distributed goodness-of-fit testing is a problem that has received considerable attention recently. The impo ... Cite

OPTIMAL HIGH-DIMENSIONAL AND NONPARAMETRIC DISTRIBUTED TESTING UNDER COMMUNICATION CONSTRAINTS

Journal Article Annals of Statistics · June 1, 2023 We derive minimax testing errors in a distributed framework where the data is split over multiple machines and their communication to a central machine is limited to b bits. We investigate both the d- and infinite-dimensional signal detection problem under ... Full text Cite

Optimal testing using combined test statistics across independent studies

Conference Advances in Neural Information Processing Systems · January 1, 2023 Combining test statistics from independent trials or experiments is a popular method of meta-analysis. However, there is very limited theoretical understanding of the power of the combined test, especially in high-dimensional models considering composite h ... Cite

Optimal Distributed Composite Testing in High-Dimensional Gaussian Models With 1-Bit Communication

Journal Article IEEE Transactions on Information Theory · June 1, 2022 In this paper we study the problem of signal detection in Gaussian noise in a distributed setting where the local machines in the star topology can communicate a single bit of information. We derive a lower bound on the Euclidian norm that the signal needs ... Full text Cite
