Mathematics for Machine Learning


Book Description

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.

Gorilla and the Bird


Book Description

"Glorious...one of the best memoirs I've read in years...a tragicomic gem about family, class, race, justice, and the spectacular weirdness of Wichita. [McDermott] can move from barely controlled hilarity to the brink of rage to aching tenderness in a single breath." -- Marya Hornbacher, New York Times Book Review Zack McDermott, a 26-year-old Brooklyn public defender, woke up one morning convinced he was being filmed, Truman Show-style, as part of an audition for a TV pilot. Every passerby was an actor; every car would magically stop for him; everything he saw was a cue from "The Producer" to help inspire the performance of a lifetime. After a manic spree around Manhattan, Zack, who is bipolar, was arrested on a subway platform and admitted to Bellevue Hospital. So begins the story of Zack's freefall into psychosis and his desperate, poignant, often hilarious struggle to claw his way back to sanity. It's a journey that will take him from New York City back to his Kansas roots and to the one person who might be able to save him, his tough, big-hearted Midwestern mother, nicknamed the Bird, whose fierce and steadfast love is the light in Zack's dark world. Before his odyssey is over, Zack will be tackled by guards in mental wards, run naked through cornfields, receive secret messages from the TV, befriend a former Navy Seal and his talking stuffed monkey, and see the Virgin Mary in the whorls of his own back hair. But with the Bird's help, he just might have a shot at pulling through, starting over, and maybe even meeting a partner who can love him back, bipolar and all. Introducing an electrifying new voice, Gorilla and the Bird is a raw and unforgettable account of a young man's unraveling and the relationship that saves him.
