Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The context tree weighting method (CTW) is a lossless compression and prediction algorithm by Willems, Shtarkov, and Tjalkens (1995) . The CTW algorithm is among the very few such algorithms that offer both theoretical guarantees and good practical performance (see, e.g., Begleiter, El-Yaniv, and Yona (2004) ). 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.
