27.05.2016: HIIT Kumpula Seminar: SCOT modeling, parallel training and statistical inference

27.05.2016 10:15–11:00

HIIT seminar

Exactum B119

Abstract:

Stochastic COntext Tree (abbreviated as SCOT) is m-Markov Chain with every state of a string independent of the symbols in its more remote past than the context of length determined by the preceding symbols of this state. SCOT has also appeared in other fields under various names (VLMC, PST, CTW) for compression applications. Consistency of algorithms for training SCOT have been derived for stationary time series with mixing.
We survey recent advances in SCOT modeling, parallel training and statistical inference described in chapter 3 of B. Ryabko, J. Astola and M. Malyutov `Compression-Based Methods of Statistical Analysis and Prediction of Time Series', Springer, which is to appear shortly.
