Guessing Based on Compressed Side Information
Robert Graczyk, Amos Lapidoth, Neri Merhav +1
A source sequence is to be guessed with some fidelity based on a rate-limited description of an observed sequence with which it is correlated. The trade-off between the description…
Gambling and Rényi Divergence
Cédric Bleuler, Amos Lapidoth, Christoph Pfister
For gambling on horses, a one-parameter family of utility functions is proposed, which contains Kelly's logarithmic criterion and the expected-return criterion as special cases. Th…
Testing Against Independence and a Rényi Information Measure
Amos Lapidoth, Christoph Pfister
The achievable error-exponent pairs for the type I and type II errors are characterized in a hypothesis testing setup where the observation consists of independent and identically…
Distributed Task Encoding
Annina Bracher, Amos Lapidoth, Christoph Pfister
The rate region of the task-encoding problem for two correlated sources is characterized using a novel parametric family of dependence measures. The converse uses a new expression…
