Mastering Java Machine Learning

By: Uday Kamath, Krishna Choppella

Overview of this book

Java is one of the main languages used by practicing data scientists; much of the Hadoop ecosystem is Java-based, and it is certainly the language that most production systems in Data Science are written in. If you know Java, Mastering Machine Learning with Java is your next step on the path to becoming an advanced practitioner in Data Science. This book aims to introduce you to an array of advanced techniques in machine learning, including classification, clustering, anomaly detection, stream learning, active learning, semi-supervised learning, probabilistic graph modeling, text mining, deep learning, and big data batch and stream machine learning. Accompanying each chapter are illustrative examples and real-world case studies that show how to apply the newly learned techniques using sound methodologies and the best Java-based tools available today. On completing this book, you will have an understanding of the tools and techniques for building powerful machine learning models to solve data science problems in just about any domain.

Vector


The vector x (lowercase, bold, by convention; equivalently, ) can be thought of as a point in n-dimensional space. Conventionally, we mean column-vector when we say vector. The transpose of a column vector is a row vector with the same number of elements, arranged in a single row.

Scalar product of vectors

Also known as the dot product, the scalar product is defined for two vectors of equal length. The result of the operation is a scalar value and is obtained by summing over the products of the corresponding elements of the vectors. Thus, given vectors x and y:

The dot product xTy is given as:
