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.

Overview of summary operations

Summaries provide a way to export condensed information about a model, which is then accessible in tools such as TensorBoard.

Some of the commonly used summary functions are:

  • scalar
  • histogram
  • audio
  • image
  • merge
  • merge_all

A scalar summary operation returns a scalar, that is, the value of a certain metric over an increasing number of epochs.

A histogram summary operation returns the histogram of various values—potentially weights and biases at each layer.

The image and audio summary operations return images and audio, which can be visualized and played in TensorBoard respectively.

A merge operation returns the union of all the values of input summaries, while merge_all returns the union of all the summaries contained in the model specification.

A visualization of some of the summaries discussed here will be provided in the next section.
