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


The multilayer perceptron is a non-parametric estimator that has been used for several decades in various industries, from insurance to image processing. It has been proven a reliable model for classification at the cost of lengthy execution.

In this chapter, you learned the origin of feedforward neural networks, how to implement the different steps of the training cycle with backpropagation in Scala, experiment with the different configuration parameters and apply the multilayer perceptron to the analysis of the fluctuations in the currencies market.

The multilayer perceptron, along with Monte Carlo sampling (Chapter 8, Monte Carlo Inference) and regularization (Chapter 9, Regression and Regularization), is a key ingredient of deep learning, which is the topic of the next chapter.
