TensorFlow Machine Learning Cookbook - Second Edition

By: Nick McClure

Overview of this book

TensorFlow is an open source software library for Machine Intelligence. The independent recipes in this book will teach you how to use TensorFlow for complex data computations and allow you to dig deeper and gain more insights into your data than ever before. With the help of this book, you will work with recipes for training models, model evaluation, sentiment analysis, regression analysis, clustering analysis, artificial neural networks, and more. You will explore RNNs, CNNs, GANs, reinforcement learning, and capsule networks, each using Google's machine learning library, TensorFlow. Through real-world examples, you will get hands-on experience with linear regression techniques with TensorFlow. Once you are familiar and comfortable with the TensorFlow ecosystem, you will be shown how to take it to production. By the end of the book, you will be proficient in the field of machine intelligence using TensorFlow. You will also have good insight into deep learning and be capable of implementing machine learning algorithms in real-world scenarios.

Using a random forest

Random forest algorithms are built on aggregating decision trees on randomly selected observations and/or randomly selected features. We will not cover how decision trees are trained, but will show that there are types of random forests that can be trained using gradient boosting, which TensorFlow can calculate for us.

Getting ready

Tree based algorithms are traditionally non-smooth, as they are based on partitioning the data to minimize the variance in the target outputs. Non-smooth methods do not lend themselves well to gradient based methods. TensorFlow relies on the fact that the functions used in the model are smooth and that it automatically calculates how to change the model parameters to minimize...
