For the more mathematically oriented, you must be wondering how exactly we descend our gradient iteratively. Well, as you know, we start by initializing random weights to our model, feed in some data, compute dot products, and pass it through our activation function along with our bias to get a predicted output. We use this predicted output and the actual output to estimate the errors in our model's representations, using the loss function. Now here comes the calculus. What we can do now is differentiate our loss function, J(θ), with respect to the weights of our model (θ). This process essentially lets us compare how changes in our model's weights affect the changes in our model's loss. The result of this differentiation gives us the gradient of our J(θ) function at the current model weight (θ) along with the direction of...

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.
