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.

Building the verification model

Now we have almost all we need to initiate the training session of our shallow autoencoder. However, we are missing one crucial component. While this part is not, strictly speaking, required to train our autoencoder, we must implement it so that we can visually verify whether our autoencoder has truly learned salient features from the training data or not. To do this, we will actually define two additional networks. Don't worry these two networks are essentially mirror images of the encoder and decoder functions that are present in the autoencoder network we just defined. Hence, all we will be doing is creating a separate encoder and decoder network, which will match the hyperparameters of the encoder and decoder functions from our autoencoder. These two separate networks will be used for prediction only after our autoencoder has been...
