Overview of this book

New experiences can be intimidating, but not this one! This beginner’s guide to deep learning is here to help you explore deep learning from scratch with Keras, and be on your way to training your first ever neural networks. What sets Keras apart from other deep learning frameworks is its simplicity. With over two hundred thousand users, Keras has a stronger adoption in industry and the research community than any other deep learning framework. The Deep Learning with Keras Workshop starts by introducing you to the fundamental concepts of machine learning using the scikit-learn package. After learning how to perform the linear transformations that are necessary for building neural networks, you'll build your first neural network with the Keras library. As you advance, you'll learn how to build multi-layer neural networks and recognize when your model is underfitting or overfitting to the training data. With the help of practical exercises, you’ll learn to use cross-validation techniques to evaluate your models and then choose the optimal hyperparameters to fine-tune their performance. Finally, you’ll explore recurrent neural networks and learn how to train them to predict values in sequential data. By the end of this book, you'll have developed the skills you need to confidently train your own neural network models.

Preface

Cross-Validation for Deep Learning Models

In this section, you will learn about using the Keras wrapper with scikit-learn, which is a helpful tool that allows us to use Keras models as part of a scikit-learn workflow. As a result, scikit-learn methods and functions, such as the one for performing cross-validation, can easily be applied to Keras models.

You will learn, step-by-step, how to implement what you learned about cross-validation in the previous section using scikit-learn. Furthermore, you will learn how to use cross-validation to evaluate Keras deep learning models using the Keras wrapper with scikit-learn. Lastly, you will practice what you have learned by solving a problem involving a real dataset.

Keras Wrapper with scikit-learn

When it comes to general machine learning and data analysis, the scikit-learn library is much richer and easier to use than Keras. That is why being able to use scikit-learn methods on Keras models will be of great value.

Fortunately...
