Advanced Deep Learning with Keras. Apply deep learning techniques, autoencoders, GANs, variational autoencoders, deep reinforcement learning, policy gradients, and more

Rowel Atienza, Neeraj Verma, Valerio Maggio

Recent developments in deep learning, including Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), and Deep Reinforcement Learning (DRL) are creating impressive AI results in our news headlines - such as AlphaGo Zero beating world chess champions, and generative AI that can create art paintings that sell for over $400k because they are so human-like.Advanced Deep Learning with Keras is a comprehensive guide to the advanced deep learning techniques available today, so you can create your own cutting-edge AI. Using Keras as an open-source deep learning library, you'll find hands-on projects throughout that show you how to create more effective AI with the latest techniques.The journey begins with an overview of MLPs, CNNs, and RNNs, which are the building blocks for the more advanced techniques in the book. You’ll learn how to implement deep learning models with Keras and TensorFlow 1.x, and move forwards to advanced techniques, as you explore deep neural network architectures, including ResNet and DenseNet, and how to create autoencoders. You then learn all about GANs, and how they can open new levels of AI performance. Next, you’ll get up to speed with how VAEs are implemented, and you’ll see how GANs and VAEs have the generative power to synthesize data that can be extremely convincing to humans - a major stride forward for modern AI. To complete this set of advanced techniques, you'll learn how to implement DRL such as Deep Q-Learning and Policy Gradient Methods, which are critical to many modern results in AI.

Advanced Express Web Application Development. For experienced JavaScript developers this book is all you need to build highly scalable, robust applications using Express. It takes you step by step through the development of a single page application so you learn empirically

Andrew Keig

Agile Development. Filozofia programowania zwinnego

James Shore, Shane Warden

Zbiór praktycznych wskazówek dla producentów oprogramowania Jak wdrożyć metodologię programowania zwinnego? W jaki sposób zaangażować klientów w projekt? Jak kontrolować jakość produktów? Programowanie zwinne (Agile Development) to obecnie jedna z najpopularniejszych metodologii zarządzania projektami programistycznymi. Metodyka Agile jest szczególnie użyteczna w małych zespołach programistycznych, w których z racji ułatwionej komunikacji nie ma potrzeby tworzenia rozbudowanej dokumentacji. Programowanie zwinne opiera się na iteracyjnej realizacji kolejnych etapów projektu. Kluczem do sukcesu w tej metodzie jest efektywna współpraca między członkami zespołu projektowego. Książka "Agile Development. Filozofia programowania zwinnego" to przewodnik po programowaniu ekstremalnym, oznaczanym zwykle skrótem XP, które jest jedną z technik wchodzących w skład tej metodyki. Czytając ją, dowiesz się, jak wdrażać metodologię Agile w firmie, na czym polega programowanie ekstremalne i jaką rolę w procesie pełnią poszczególni członkowie grupy projektowej. Nauczysz się budować zespół i określać zakresy zadań osób biorących udział w pracach, planować harmogram udostępniania kolejnych wersji produktu oraz kierować procesem jego tworzenia. Poznasz metody testowania programu i usuwania z niego błędów, zasady pisania dokumentacji oraz reguły prowadzenia spotkań roboczych z klientami. Wdrażanie programowania zwinnego Techniki programowania ekstremalnego Członkowie zespołu XP Zarządzanie zespołem Angażowanie klienta w proces wytwórczy Tworzenie raportów Udostępnianie kolejnych wersji systemu Standardy pisania kodu Testowanie i usuwanie błędów Optymalizacja wydajności programu Od filozofii do mistrzostwa w zwinnym programowaniu!
