Locally Private Parametric Methods for Change-Point Detection
Anuj Kumar Yadav, Cemre Cadir, Yanina Shkel +1
We study parametric change-point detection, where the goal is to identify distributional changes in time series, under local differential privacy. In the non-private setting, we de…

Log-Likelihood Loss for Semantic Compression
Anuj Kumar Yadav, Dan Song, Yanina Shkel +1
We study lossy source coding under a distortion measure defined by the negative log-likelihood induced by a prescribed conditional distribution . This \emph{log-likelihood…
