These three books by highly respected academics / practitioners, and cover some of the most popular techniques in data mining and machine learning today. The previous section, Statistical Machine Learning, covers machine learning from the perspective of statisticians: creating statistical valid models of the data that can be used for predictions. This section, practical machine learning / data mining, deals more with the need to extract information and make predictions from large datasets. The first book, [ADVANCED] Mining of Massive Datasets, is based off of Stanford's eponymous class, and covers popular problems such as recommendation systems, PageRank, and social network analysis.
