Ullman  a3rd ed.  aCambridge :bCambridge University Press,c2020  axi, 553 p.  aIncludes bibliographical references and index.  a"The Web, social media, mobile activity, sensors, Internet commerce, and many other modern applications provide many extremely large datasets from which information can be gleaned by data mining. This book focuses on practical algorithms that have been used to solve key problems in data mining and can be used on even the largest datasets. It begins with a discussion of the MapReduce framework and related techniques for efficient parallel programming. The tricks of locality-sensitive hashing are explained. This body of knowledge, which deserves to be more widely known, is essential when seeking similar objects in a very large collection without having to compare each pair of objects. Stream-processing algorithms for mining data that arrives too fast for exhaustive processing are also explained. The PageRank idea and related tricks for organizing the Web are covered next. Other chapters cover the problems of finding frequent itemsets and clustering, each from the point of view that the data is too large to fit in main memory. Two applications: recommendation systems and Web advertising, each vital in e-commerce, are treated in detail. Later chapters cover algorithms for analyzing social-network graphs, compressing large-scale data, and machine learning. This third edition includes new and extended coverage on decision trees, deep learning, and mining social-network graphs. Written by leading authorities in database and Web technologies, it is essential reading for students and practitioners alike"-- Provided by publisher  aEng  aBig Data  aData Mining1 aRajaraman, Anand9155261 aUllman, Jeffrey D.915527  cBK  c142527d142527  00104070a01b01d2026-09-15l0oT 006.312 LES-Mp154399r2026-09-15 14:47:09w2026-09-15yBK  00104070a01b01d2026-09-15l0oT 006.312 LES-Mp154400r2026-09-15 14:47:16tC.2w2026-09-15yBK  00104070a01b01d2026-09-15l0oT 006.312 LES-Mp154401r2026-09-15 14:47:23tC.3w2026-09-15yBK  00104070a01b01d2026-09-15l0oT 006.312 LES-Mp154402r2026-09-15 14:47:31tC.4w2026-09-15yBK  00104070a01b01d2026-09-15l0oT 006.312 LES-Mp154403r2026-09-15 14:47:45tC.5w2026-09-15yBK
