An introduction to a broad range of topics in deep learning, covering mathematical and conceptual background, deep learning techniques used in industry, and research perspectives. “Written by three experts in the field, Deep Learning is the only comprehensive book on the subject.” —Elon Musk, cochair of OpenAI; cofounder and CEO of Tesla and SpaceX Deep learning is a form of machine learning that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts. Because the computer gathers knowledge from experience, there is no need for a human computer operator to formally specify all the knowledge that the computer needs. The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning. The text offers mathematical and conceptual background, covering relevant concepts in linear algebra, probability theory and information theory, numerical computation, and machine learning. It describes deep learning techniques used by practitioners in industry, including deep feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling, and practical methodology; and it surveys such applications as natural language processing, speech recognition, computer vision, online recommendation systems, bioinformatics, and videogames. Finally, the book offers research perspectives, covering such theoretical topics as linear factor models, autoencoders, representation learning, structured probabilistic models, Monte Carlo methods, the partition function, approximate inference, and deep generative models. Deep Learning can be used by undergraduate or graduate students planning careers in either industry or research, and by software engineers who want to begin using deep learning in their products or platforms. A website offers supplementary material for both readers and instructors.

Revised and updated "One of today’s most respected journalists, David Rohde takes on one of the country’s most toxic conspiracy theories," presenting a "scrupulously reported and even-handed" account of how power and intelligence are exploited in Washington that “goes deep indeed inside America’s security state, telling a story that will surprise readers of all political persuasions” (Jane Mayer, author of Dark Money). Donald Trump blamed his 2020 defeat on Democrats and the “deep state”—a supposed secret cabal of Washington insiders that relentlessly encroaches on the individual rights of Americans—for stealing the election and undermining his presidency. Most Americans who supported him agreed. Americans on the left increasingly fear the “military-industrial complex,” a faction of generals and defense contractors who they believe routinely push the country into endless wars. But does the American “deep state” really exist? This question is fundamental to preserving the legitimacy of American democracy, as frustration with and distrust for the government continue to grow. In Deep seeks to dispel these pernicious myths through an examination of the FBI, CIA, and Justice Department scandals of the past fifty years from the Church Committee’s exposure of Cold War abuses to the claims and counterclaims of the Trump era and the relentless spread of conspiracy theories online and on air. It exposes the misconduct of Attorney General William Barr; how distrust of the “deep state” undermined the US government response to the COVID-19 pandemic; and the growing discord sowed by the explosion of false information online. It investigates Trump’s quest to discredit government experts, the legislative and judicial branches, and the results of the 2020 election and assume authoritarian power for himself. “The idea of the deep state, Rohde writes, is inextricably linked to a particular view of presidential power” (Dina Temple-Raston, Washington Post). Based on dozens of interviews with career CIA operatives and FBI agents, “In Deep is a wholly satisfying read and a necessary one for anyone wanting to understand the forces at play in our government today” (Andrea Bernstein, Peabody Award–winning cohost of the Trump, Inc. podcast and author of American Oligarchs).

Ultracompetitive Brynn from The Summer of Firsts and Lasts craves swimming victory—and gets in over her head—in this irresistible novel from Terra Elan McVoy. Swim. Push. Breathe. Swim. Nothing else matters to Brynn as she trains her body and mind to win. Not her mediocre grades and lack of real friends at school. Not the gnawing grief over her fallen hero father. Not the strained relationship with her absent mother and clueless stepdad. In the turquoise water, swimming is an escape and her ticket to somewhere—anywhere—else. And nothing will get in her way of claiming victory. But when the competitive streak follows Brynn out of the pool in a wickedly seductive cat-and-mouse game between herself, her wild best friend, and a hot new college swimmer, Brynn’s single-mindedness gets her in over her head, with much more than a trophy to lose.

On the evening of August 30, 2003, Robert and Melissa Rogers and their four young children were driving home from a family wedding. Caught in a flash flood, Melissa and the children all drowned. Into the Deep is the compelling story of how one man's faith took root and blossomed through trials, blessings, and a deepening trust in God.

The starting point for In Deep Waters: Spiritual Care for Young People in a Climate Crisis is not news: the world as we know it is shifting. Several millennia of climate stability have come to an abrupt end. But, observes Talitha Amadea Aho, the young people of today do not remember stability. They see the world through crisis-colored glasses. Climate change is creating a spiritual emergency that is hitting their generation harder than any other. Today's climate crisis calls people of faith to a communal spiritual practice of care, especially for those who are more vulnerable because of their youth--the children, youth, and young adults of Generation Z. We must learn how to offer spiritual care that is informed by the spiritual-ecological crisis of their generation. This book will help you keep young people at the center of your community and listen to the troubles they have to share. Whether you are a Gen Z peer or a caring adult of any other generation, In Deep Water will show you how to offer ecologically informed spiritual care. We all need to do it today; we cannot wait until one of today's youngest generations grows up.

Following Jesus doesn’t guarantee sunny skies and smooth sailing. In fact, the waters of life are often tumultuous, crashing over us. Sometimes we can feel that we’re drowning in a sea of confusion, division, frustration, complacency, or disillusionment. We need more than a shallow faith to survive these deep waters. Into the Deep is an invitation to dive headfirst into a life of courageous faith. With endearing warmth and authenticity, Lauren Gaskill shares how she and others have learned to swim with Jesus in the deep waters of life—facing challenges such as anxiety, depression, and chronic illness—only to discover a more authentic, enduring faith that cannot be shaken by circumstances. In addition to examining the character of God and the lives of women and men of the Bible who chose to dive deeper with God, she provides practical examples and tools that help us take our faith to the next level by learning to make decisions by faith alone, control our reactions to overwhelming situations, and live a life rooted in love. Get ready to exchange fear and frustration for the boldness, courage, and holy confidence that lead to a life of deep faith and joy!
