This book provides an introduction to the mathematical and algorithmic foundations of data science, including machine learning, high-dimensional geometry, and analysis of large networks. Topics include the counterintuitive nature of data in high dimensions, important linear algebraic techniques such as singular value decomposition, the theory of random walks and Markov chains, the fundamentals of and important algorithms for machine learning, algorithms and analysis for clustering, probabilistic models for large networks, representation learning including topic modelling and non-negative matrix factorization, wavelets and compressed sensing. Important probabilistic techniques are developed including the law of large numbers, tail inequalities, analysis of random projections, generalization guarantees in machine learning, and moment methods for analysis of phase transitions in large random graphs. Additionally, important structural and complexity measures are discussed such as matrix norms and VC-dimension. This book is suitable for both undergraduate and graduate courses in the design and analysis of algorithms for data.

"Time travel, UFOs, mysterious planets, stigmata, rock-throwing poltergeists, huge footprints, bizarre rains of fish and frogs-nearly a century after Charles Fort's Book of the Damned was originally published, the strange phenomenon presented in this book remains largely unexplained by modern science. Through painstaking research and a witty, sarcastic style, Fort captures the imagination while exposing the flaws of popular scientific explanations. Virtually all of his material was compiled and documented from reports published in reputable journals, newspapers and periodicals because he was an avid collector. Charles Fort was somewhat of a recluse who spent most of his spare time researching these strange events and collected these reports from publications sent to him from around the globe. This was the first of a series of books he created on unusual and unexplained events and to this day it remains the most popular. If you agree that truth is often stranger than fiction, then this book is for you"--Taken from Good Reads website.
