Today that number is one percent. What went so wrong? Losing the Signal is a riveting story of a company that toppled global giants before succumbing to the ruthlessly competitive forces of Silicon Valley. This is not a conventional tale of modern business failure by fraud and greed. The rise and fall of BlackBerry reveals the dangerous speed at which innovators race along the information superhighway. With unprecedented access to key players, senior executives, directors and competitors, Losing the Signal unveils the remarkable rise of a company that started above a bagel store in Ontario. At the heart of the story is an unlikely partnership between a visionary engineer, Mike Lazaridis, and an abrasive Harvard Business school grad, Jim Balsillie. Together, they engineered a pioneering pocket email device that became the tool of choice for presidents and CEOs. The partnership enjoyed only a brief moment on top of the world, however. At the very moment BlackBerry was ranked the world's fastest growing company internal feuds and chaotic growth crippled the company as it faced its gravest test: Apple and Google's entry in to mobile phones. Expertly told by acclaimed journalists, Jacquie McNish and Sean Silcoff, this is an entertaining, whirlwind narrative that goes behind the scenes to reveal one of the most compelling business stories of the new century.

    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.

    At the time, only three percent of Americans were online. It took a decade for AOL to achieve mainstream success, and there were many near-death experiences and back-to-the-wall pivots. AOL became the top performing company of the 1990s, and at its peak more than half of all consumer internet traffic in the United States ran through the service. After Case engineered AOL’s merger with Time Warner and he became Chairman of the combined business, Case oversaw the biggest media and communications empire in the world. In The Third Wave, which pays homage to the work of the futurist Alvin Toffler (from whom Case has borrowed the title, and whose work inspired him as a young man), Case takes us behind the scenes of some of the most consequential and riveting business decisions of our time while offering illuminating insights from decades of working as an entrepreneur, an investor, a philanthropist, and an advocate for sensible bipartisan policies. We are entering, as Case explains, a new paradigm called the “Third Wave” of the internet. The first wave saw AOL and other companies lay the foundation for consumers to connect to the Internet. The second wave saw companies like Google and Facebook build on top of the Internet to create search and social networking capabilities, while apps like Snapchat and Instagram leverage the smartphone revolution. Now, Case argues, we’re entering the Third Wave: a period in which entrepreneurs will vastly transform major “real world” sectors like health, education, transportation, energy, and food—and in the process change the way we live our daily lives. But success in the Third Wave will require a different skill set, and Case outlines the path forward. The Third Wave is part memoir, part manifesto, and part playbook for the future. With passion and clarity, Case explains the ways in which newly emerging technology companies (a growing number of which, he argues, will not be based in Silicon Valley) will have to rethink their relationships with customers, with competitors, and with governments; and offers advice for how entrepreneurs can make winning business decisions and strategies—and how all of us can make sense of this changing digital age.
