Scala for Machine Learning, Second Edition - Second Edition

Overview of this book

The discovery of information through data clustering and classification is becoming a key differentiator for competitive organizations. Machine learning applications are everywhere, from self-driving cars, engineering design, logistics, manufacturing, and trading strategies, to detection of genetic anomalies. The book is your one stop guide that introduces you to the functional capabilities of the Scala programming language that are critical to the creation of machine learning algorithms such as dependency injection and implicits. You start by learning data preprocessing and filtering techniques. Following this, you'll move on to unsupervised learning techniques such as clustering and dimension reduction, followed by probabilistic graphical models such as Naïve Bayes, hidden Markov models and Monte Carlo inference. Further, it covers the discriminative algorithms such as linear, logistic regression with regularization, kernelization, support vector machines, neural networks, and deep learning. You’ll move on to evolutionary computing, multibandit algorithms, and reinforcement learning. Finally, the book includes a comprehensive overview of parallel computing in Scala and Akka followed by a description of Apache Spark and its ML library. With updated codes based on the latest version of Scala and comprehensive examples, this book will ensure that you have more than just a solid fundamental knowledge in machine learning with Scala.

Summary


This concludes our journey into the unsettling world of evolutionary computing. There is a lot more to evolutionary computing than genetic algorithms such as artificial life, swarm intelligence, or differential evolution. Moreover, our description of genetic algorithm did not include genetic programming that applies genetic operators to trees and directed graphs of expressions.

This chapter dealt with a review of the different NP problems, the key components and genetic operators, an application of the fitness score to financial trading strategy, and the subtle variation in encoding predicates. The chapter concluded with an overview of the advantages and risks of genetic algorithms.

Genetic algorithms are an important element of a special class of reinforcement learning introduced in the Learning classifiers systems section of Chapter 15, Reinforcement learning. The next two chapters describe the most common reinforcement learning techniques starting with Bayesian inference algorithms...
