Overview of this book

Getting to grips with tensors, deep learning, and neural networks can be intimidating and confusing for anyone, no matter their experience level. The breadth of information out there, often written at a very high level and aimed at advanced practitioners, can make getting started even more challenging. If this sounds familiar to you, The TensorFlow Workshop is here to help. Combining clear explanations, realistic examples, and plenty of hands-on practice, it’ll quickly get you up and running. You’ll start off with the basics – learning how to load data into TensorFlow, perform tensor operations, and utilize common optimizers and activation functions. As you progress, you’ll experiment with different TensorFlow development tools, including TensorBoard, TensorFlow Hub, and Google Colab, before moving on to solve regression and classification problems with sequential models. Building on this solid foundation, you’ll learn how to tune models and work with different types of neural network, getting hands-on with real-world deep learning applications such as text encoding, temperature forecasting, image augmentation, and audio processing. By the end of this deep learning book, you’ll have the skills, knowledge, and confidence to tackle your own ambitious deep learning projects with TensorFlow.

Summary

You started your journey in this chapter with an introduction to the different scenarios of training a model. A model is overfitting when its performance is much better on the training set than the test set. An underfitting model is one that can achieve good results only after training. Finally, a good model achieves good performance on both the training and test sets.

Then, you encountered several regularization techniques that can help prevent a model from overfitting. You first looked at the L1 and L2 regularizations, which add a penalty component to the cost function. This additional penalty helps to simplify the model by reducing the weights of some features. Then, you went through two different techniques specific to neural networks: dropout and early stopping. Dropout randomly drops some units in the model architecture and forces it to consider other features to make predictions. Early stopping is a mechanism that automatically stops the training of a model once the...
