Book Description
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.

Book Description
Every president has had a unique and complicated relationship with the intelligence community. While some have been coolly distant, even adversarial, others have found their intelligence agencies to be among the most valuable instruments of policy and power. Since John F. Kennedy's presidency, this relationship has been distilled into a personalized daily report: a short summary of what the intelligence apparatus considers the most crucial information for the president to know that day about global threats and opportunities. This top-secret document is known as the President's Daily Brief, or, within national security circles, simply "the Book." Presidents have spent anywhere from a few moments (Richard Nixon) to a healthy part of their day (George W. Bush) consumed by its contents; some (Bill Clinton and George H. W. Bush) consider it far and away the most important document they saw on a regular basis while commander in chief. The details of most PDBs are highly classified, and will remain so for many years. But the process by which the intelligence community develops and presents the Book is a fascinating look into the operation of power at the highest levels. David Priess, a former intelligence officer and daily briefer, has interviewed every living president and vice president as well as more than one hundred others intimately involved with the production and delivery of the president's book of secrets. He offers an unprecedented window into the decision making of every president from Kennedy to Obama, with many character-rich stories revealed here for the first time.

Book Description
A Darker Shade of Magic, from #1 New York Times bestselling author V.E. Schwab Kell is one of the last Antari—magicians with a rare, coveted ability to travel between parallel Londons; Red, Grey, White, and, once upon a time, Black. Kell was raised in Arnes—Red London—and officially serves the Maresh Empire as an ambassador, traveling between the frequent bloody regime changes in White London and the court of George III in the dullest of Londons, the one without any magic left to see. Unofficially, Kell is a smuggler, servicing people willing to pay for even the smallest glimpses of a world they'll never see. It's a defiant hobby with dangerous consequences, which Kell is now seeing firsthand. After an exchange goes awry, Kell escapes to Grey London and runs into Delilah Bard, a cut-purse with lofty aspirations. She first robs him, then saves him from a deadly enemy, and finally forces Kell to spirit her to another world for a proper adventure. Now perilous magic is afoot, and treachery lurks at every turn. To save all of the worlds, they'll first need to stay alive. "A Darker Shade of Magic has all the hallmarks of a classic work of fantasy. Schwab has given us a gem of a tale...This is a book to treasure."—Deborah Harkeness, New York Times bestselling author of the All Souls trilogy Shades of Magic series 1. A Darker Shade of Magic 2. A Gathering of Shadows 3. A Conjuring of Light At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Book Description
This newly expanded and updated second edition of the best-selling classic continues to take the "mystery" out of designing algorithms, and analyzing their efficacy and efficiency. Expanding on the first edition, the book now serves as the primary textbook of choice for algorithm design courses while maintaining its status as the premier practical reference guide to algorithms for programmers, researchers, and students. The reader-friendly Algorithm Design Manual provides straightforward access to combinatorial algorithms technology, stressing design over analysis. The first part, Techniques, provides accessible instruction on methods for designing and analyzing computer algorithms. The second part, Resources, is intended for browsing and reference, and comprises the catalog of algorithmic resources, implementations and an extensive bibliography. NEW to the second edition: • Doubles the tutorial material and exercises over the first edition • Provides full online support for lecturers, and a completely updated and improved website component with lecture slides, audio and video • Contains a unique catalog identifying the 75 algorithmic problems that arise most often in practice, leading the reader down the right path to solve them • Includes several NEW "war stories" relating experiences from real-world applications • Provides up-to-date links leading to the very best algorithm implementations available in C, C++, and Java
