TensorFlow: Powerful Predictive Analytics with TensorFlow

By: Md. Rezaul Karim

Overview of this book

Predictive analytics discovers hidden patterns from structured and unstructured data for automated decision making in business intelligence. Predictive decisions are becoming a huge trend worldwide, catering to wide industry sectors by predicting which decisions are more likely to give maximum results. TensorFlow, Google’s brainchild, is immensely popular and extensively used for predictive analysis. This book is a quick learning guide on all the three types of machine learning, that is, supervised, unsupervised, and reinforcement learning with TensorFlow. This book will teach you predictive analytics for high-dimensional and sequence data. In particular, you will learn the linear regression model for regression analysis. You will also learn how to use regression for predicting continuous values. You will learn supervised learning algorithms for predictive analytics. You will explore unsupervised learning and clustering using K-meansYou will then learn how to predict neighborhoods using K-means, and then, see another example of clustering audio clips based on their audio features. This book is ideal for developers, data analysts, machine learning practitioners, and deep learning enthusiasts who want to build powerful, robust, and accurate predictive models with the power of TensorFlow. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from material from Packt's Predictive Analytics with TensorFlow by Md. Rezaul Karim.

Preface

Unsupervised Learning and Clustering


In this section, we will provide a brief introduction to the unsupervised machine learning (ML) technique. Unsupervised learning is a type of ML algorithm used for grouping related data objects and finding hidden patterns by inferencing from unlabeled datasets, that is, a training set consisting of input data without labels.

Let's see a real-life example. Suppose you have a large collection of not-pirated-totally-legal MP3s in a crowded and massive folder on your hard drive. Now, what if you can build a predictive model that helps automatically group together similar songs and organize them into your favorite categories such as country, rap, and rock?

This is an act of assigning an item to a group so that an MP3 is added to the respective playlist in an unsupervised way. In Lesson 1, From Data to Decisions – Getting Started with TensorFlow, on classification, we assumed that you're given a training dataset of correctly labeled data. Unfortunately, we don...
