On the Possibility of Learning in Reactive Environments with Arbitrary Dependence
Daniil Ryabko, Marcus Hutter
We address the problem of reinforcement learning in which observations may exhibit an arbitrary form of stochastic dependence on past observations and actions, i.e. environments mo…
Constructing Perfect Steganographic Systems
Boris Ryabko, Daniil Ryabko
We propose steganographic systems for the case when covertexts (containers) are generated by a finite-memory source with possibly unknown statistics. The probability distributions…
An impossibility result for process discrimination
Daniil Ryabko
Two series of binary observations and are presented: at each time we are given and . It is assumed that the sequences are generated…
Nonparametric Statistical Inference for Ergodic Processes
Daniil Ryabko, Boris Ryabko
In this work a method for statistical analysis of time series is proposed, which is used to obtain solutions to some classical problems of mathematical statistics under the only as…
