Risk level dependent Minimax Quantile lower bounds for Interactive Statistical Decision Making
Raghav Bongole, Amirreza Zamani, Tobias J. Oechtering +1
Minimax risk and regret focus on expectation, missing rare failures critical in safety-critical bandits and reinforcement learning. Minimax quantiles capture these tails. Three str…
Integrated Sensing and Communication with Distributed Rate-Limited Helpers
Yiqi Chen, Holger Boche, Tobias J. Oechtering +1
This paper studies integrated sensing and communication (ISAC) systems with two rate-limited helpers who observe the channel state sequence and the feedback sequence, respectively.…
Zero Estimation Cost Strategy for Witsenhausen Counterexample with Causal Encoder
Mengyuan Zhao, Tobias J. Oechtering, Maël Le Treust
We propose a zero estimation cost (ZEC) scheme for causal-encoding noncausal-decoding vector-valued Witsenhausen counterexample based on the coordination coding result. In contrast…
Multi-terminal Strong Coordination over Noisy Channels with Encoder Co-operation
Viswanathan Ramachandran, Tobias J. Oechtering, Mikael Skoglund
We investigate the problem of strong coordination over a multiple-access channel (MAC) with cribbing encoders. In this configuration, two encoders observe independent and identical…
Bounds on the privacy amplification of arbitrary channels via the contraction of -divergence
Leonhard Grosse, Sara Saeidian, Tobias J. Oechtering +1
We examine the privacy amplification of channels that do not necessarily satisfy any LDP guarantee by analyzing their contraction behavior in terms of -divergence, an -dive…
