In this chapter, you learned about the basics of deep learning, including the common representations and terminology and essential underlying concepts. You learned how forward propagation in neural networks works and how it is used for predicting outputs. You learned about the loss function as a measure of model performance and learned how backpropagation is used to compute the derivatives of loss function with respect to model parameters. Finally, you learned about gradient descent, which uses the gradients computed by backpropagation to gradually update the model parameters. In addition to basic theory and concepts, you also learned how to implement and train shallow and deep neural networks with Keras and how to use a trained network to make predictions about the output of a given input. You also learned how to evaluate the overall performance of the network over all data examples, and the reasons why evaluating a model on training examples can be misleading. You learned about...

#### Overview of this book

Though designing neural networks is a sought-after skill, it is not easy to master. With Keras, you can apply complex machine learning algorithms with minimum code.
Applied Deep Learning with Keras starts by taking you through the basics of machine learning and Python all the way to gaining an in-depth understanding of applying Keras to develop efficient deep learning solutions. To help you grasp the difference between machine and deep learning, the book guides you on how to build a logistic regression model, first with scikit-learn and then with Keras. You will delve into Keras and its many models by creating prediction models for various real-world scenarios, such as disease prediction and customer churning. You’ll gain knowledge on how to evaluate, optimize, and improve your models to achieve maximum information. Next, you’ll learn to evaluate your model by cross-validating it using Keras Wrapper and scikit-learn. Following this, you’ll proceed to understand how to apply L1, L2, and dropout regularization techniques to improve the accuracy of your model. To help maintain accuracy, you’ll get to grips with applying techniques including null accuracy, precision, and AUC-ROC score techniques for fine tuning your model.
By the end of this book, you will have the skills you need to use Keras when building high-level deep neural networks.
