Artificial Intelligence became one of the hottest topics in the modern economy, where everything is driven by software, network and data. There exists nearly no startup nor traditional business where Artificial Intelligence is not used extensively across many fields such as search engines, image recognition, robotics or finance. This book gives a ground up, step by step introduction about how a Neural Network is used to learn a given function and to make intelligent data-driven decisions. In this book, you will learn:How to ensure success in building artificial intelligence products, How to mitigate risks through best practices, How to create a long-lasting value with artificial intelligence, How to prevent mistakes to build artificial intelligence solutions. This revised and fully updated fourth edition contains several new sections, covering a broader set of topics than before, but retains the no-nonsense style of the original. Artificial Intelligence (AI) and Machine Learning are now mainstream business tools. They are being applied across many industries to increase profits, reduce costs, save lives and improve customer experiences. Consequently, organizations that understand these tools and know how to use them are benefiting at the expense of their rivals.
