Optimal Gaussian Strategies for Vector-valued Witsenhausen Counterexample with Non-causal State Estimator
Mengyuan Zhao, Tobias J. Oechtering, Maël Le Treust
In this study, we investigate a vector-valued Witsenhausen model where the second decision maker (DM) acquires a vector of observations before selecting a vector of estimations. He…
Causal Vector-valued Witsenhausen Counterexamples with Feedback
Mengyuan Zhao, Maël Le Treust, Tobias J. Oechtering
We study the continuous vector-valued Witsenhausen counterexample through the lens of empirical coordination coding. We characterize the region of achievable pairs of costs in thre…
Chained Information-Theoretic bounds and Tight Regret Rate for Linear Bandit Problems
Amaury Gouverneur, Borja Rodríguez-Gálvez, Tobias J. Oechtering +1
This paper studies the Bayesian regret of a variant of the Thompson-Sampling algorithm for bandit problems. It builds upon the information-theoretic framework of [Russo and Van Roy…
Quantifying Privacy via Information Density
Leonhard Grosse, Sara Saeidian, Parastoo Sadeghi +2
We examine the relationship between privacy metrics that utilize information density to measure information leakage between a private and a disclosed random variable. Firstly, we p…
On General Capacity-Distortion Formulas of Integrated Sensing and Communication
Yiqi Chen, Tobias Oechtering, Mikael Skoglund +1
The integrated sensing and communication (ISAC) problem with general state and channel distributions is investigated. General formulas of the capacity-distortion tradeoff for the I…
Private Variable-Length Coding with Sequential Encoder
Amirreza Zamani, Tobias J. Oechtering, Deniz Gündüz +1
A multi-user private data compression problem is studied. A server has access to a database of files, , each of size bits and is connected to an encoder. The…
