Machine Learning Using TensorFlow Cookbook

By: Luca Massaron, Alexia Audevart, Konrad Banachewicz

Overview of this book

The independent recipes in Machine Learning Using TensorFlow Cookbook will teach you how to perform complex data computations and gain valuable insights into your data. Dive into recipes on training models, model evaluation, sentiment analysis, regression analysis, artificial neural networks, and deep learning - each using Google’s machine learning library, TensorFlow. This cookbook covers the fundamentals of the TensorFlow library, including variables, matrices, and various data sources. You’ll discover real-world implementations of Keras and TensorFlow and learn how to use estimators to train linear models and boosted trees, both for classification and regression. Explore the practical applications of a variety of deep learning architectures, such as recurrent neural networks and Transformers, and see how they can be used to solve computer vision and natural language processing (NLP) problems. With the help of this book, you will be proficient in using TensorFlow, understand deep learning from the basics, and be able to implement machine learning algorithms in real-world scenarios.

Implementing unit tests

Testing code results in faster prototyping, more efficient debugging, faster changing, and makes it easier to share code. TensorFlow 2.0 provides the tf.test module and we will cover it in this recipe.

Getting ready

When programming a TensorFlow model, it helps to have unit tests to check the functionality of the program. This helps us because when we want to make changes to a program unit, tests will make sure those changes do not break the model in unknown ways. In Python, the main test framework is unittest but TensorFlow provides its own test framework. In this recipe, we will create a custom layer class. We will implement a unit test to illustrate how to write it in TensorFlow.

How to do it...

  1. First, we need to load the necessary libraries as follows:
    import tensorflow as tf
    import numpy as np
    
  2. Then, we need to declare our custom gate that applies the function f(x) = a1 * x + b1:
    class MyCustomGate(tf...
