F# for Machine Learning Essentials

By: Sudipta Mukherjee

Overview of this book

The F# functional programming language enables developers to write simple code to solve complex problems. With F#, developers create consistent and predictable programs that are easier to test and reuse, simpler to parallelize, and are less prone to bugs. If you want to learn how to use F# to build machine learning systems, then this is the book you want. Starting with an introduction to the several categories on machine learning, you will quickly learn to implement time-tested, supervised learning algorithms. You will gradually move on to solving problems on predicting housing pricing using Regression Analysis. You will then learn to use Accord.NET to implement SVM techniques and clustering. You will also learn to build a recommender system for your e-commerce site from scratch. Finally, you will dive into advanced topics such as implementing neural network algorithms while performing sentiment analysis on your data.

Chapter 7. Anomaly Detection

"Find the odd one out automatically."

Anomaly Detection is the art of finding the odd one out in a bunch of data automatically. As the name suggests, it is the science of finding the data that is anomalous compared to the other. However, there are several kinds of anomalies; sometimes the normal (non-anomalous) data can be line anomalous data. Anomaly detection is mostly an unsupervised learning problem because it is very difficult, if not impossible, to get a labeled training dataset that is anomalous. Sometimes, anomalies are referred to as "outliers."
