Hands-On Neural Networks with Keras

By: Niloy Purkait

Overview of this book

Neural networks are used to solve a wide range of problems in different areas of AI and deep learning. Hands-On Neural Networks with Keras will start with teaching you about the core concepts of neural networks. You will delve into combining different neural network models and work with real-world use cases, including computer vision, natural language understanding, synthetic data generation, and many more. Moving on, you will become well versed with convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory (LSTM) networks, autoencoders, and generative adversarial networks (GANs) using real-world training datasets. We will examine how to use CNNs for image recognition, how to use reinforcement learning agents, and many more. We will dive into the specific architectures of various networks and then implement each of them in a hands-on manner using industry-grade frameworks. By the end of this book, you will be highly familiar with all prominent deep learning models and frameworks, and the options you have when applying deep learning to real-world scenarios and embedding artificial intelligence as the core fabric of your organization.

Exercise

  • Implement standard Q-learning with a different policy (Boltzman) on an Atari environment and examine the difference in performance metrics
  • Implement a Double DQN on the same problem and compare the difference in performance
  • Implement a Dueling DQN for the same problem and compare the difference in performance

Limits of Q-learning

It is truly remarkable how a relatively simple algorithm as such can give rise to complex strategies that such agents can come up with, given enough training time. Notably, researchers (and now, you too) are able to show how expert strategies may be learned through enough interaction with the environment. In the classic game of breakout, for example (included as an environment in the Atari...
