Context tree weighting
Appearance
The context tree weighting method (CTW) is a lossless compression and prediction algorithm by Willems, Shtarkov, and Tjalkens (1995), {{citation}}

The CTW algorithm is an “ensemble method,” mixing the predictions of many underlying variable order Markov models, where each such model is constructed using zero-order conditional probability estimators.
