Fast Recursive Coding Based on Grouping of Symbols
Nikolay Ponomarenko, Vladimir Lukin, Karen Egiazarian +2
A novel fast recursive coding technique is proposed. It operates with only integer values not longer 8 bits and is multiplication free. Recursion the algorithm is based on indirect…
Universal Codes as a Basis for Time Series Testing
Boris Ryabko, Jaakko Astola
We suggest a new approach to hypothesis testing for ergodic and stationary processes. In contrast to standard methods, the suggested approach gives a possibility to make tests, bas…
Universal Codes as a Basis for Nonparametric Testing of Serial Independence for Time Series
Boris Ryabko, Jaakko Astola
We consider a stationary and ergodic source generated symbols from some finite set and a null hypothesis that is Markovian source with memory (or co…
Prediction of Large Alphabet Processes and Its Application to Adaptive Source Coding
Boris Ryabko, Jaakko Astola
The problem of predicting a sequence generated by a discrete source with unknown statistics is considered. Each letter is predicted using information on the…
Fast Codes for Large Alphabets
Boris Ryabko, Jaakko Astola, Karen Egiazarian
We address the problem of constructing a fast lossless code in the case when the source alphabet is large. The main idea of the new scheme may be described as follows. We group let…
