Hands-On Machine Learning on Google Cloud Platform

By: Giuseppe Ciaburro, V Kishore Ayyadevara, Alexis Perrier

Overview of this book

Google Cloud Machine Learning Engine combines the services of Google Cloud Platform with the power and flexibility of TensorFlow. With this book, you will not only learn to build and train different complexities of machine learning models at scale but also host them in the cloud to make predictions. This book is focused on making the most of the Google Machine Learning Platform for large datasets and complex problems. You will learn from scratch how to create powerful machine learning based applications for a wide variety of problems by leveraging different data services from the Google Cloud Platform. Applications include NLP, Speech to text, Reinforcement learning, Time series, recommender systems, image classification, video content inference and many other. We will implement a wide variety of deep learning use cases and also make extensive use of data related services comprising the Google Cloud Platform ecosystem such as Firebase, Storage APIs, Datalab and so forth. This will enable you to integrate Machine Learning and data processing features into your web and mobile applications. By the end of this book, you will know the main difficulties that you may encounter and get appropriate strategies to overcome these difficulties and build efficient systems.

Generative models

A generative model aims to generate all the values of a phenomenon, both those that can be observed (input) and those that can be calculated from the ones observed (target). We try to understand how such a model can succeed in this goal by proposing a first distinction between generative and discriminative models.

Often, in machine learning, we need to predict the value of a target vector y given the value of an input x vector. From a probabilistic perspective, the goal is to find the conditional probability distribution p(y|x).

The conditional probability of an event y with respect to an event x is the probability that y occurs, knowing that x is verified. This probability, indicated by p(y|x), expresses a correction of expectations for y, dictated by the observation of x.

The most common approach to this problem is to represent the conditional distribution...
