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…
Two Measures of Dependence
Amos Lapidoth, Christoph Pfister
Two families of dependence measures between random variables are introduced. They are based on the Rényi divergence of order and the relative -entropy, respectively, and bot…
