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.

Convolutional layer

Two main architectural considerations are associated with the convolutional layer in Keras. The first is to do with the number of filters to employ in the given layer, whereas the second denotes the size of the filters themselves. So, let's see how this is implemented by initializing a blank sequential model and adding our first convolutional layer to it:

model=sequential()
#First Convolutional layer model.add(Conv2D(16,(5,5), padding = 'same', activation = 'relu', input_shape = (64,64,3))) model.add(BatchNormalization())

Defining the number and size of the filters

As we saw previously, we define the layer by embodying it with 16 filters, each with a height and width of 5 x 5. In...
