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 4. Information Retrieval

"Ways to find a needle in haystack"

Information overload is almost a passé term; however, it is still valid. Information retrieval is a big arena and most of it is far from being solved. However, that being said, we have come a long way and the results produced by some of the state-of-the-art information retrieval algorithms are really impressive. You may not know that you are using information retrieval but whenever you search for some documents on your PC or on the internet, you are actually using the product of an information retrieval algorithm in the background. So as the metaphor goes, finding the needle (read information/insight) in a haystack (read your data archive on your PC or on the web) is the key to successful business. This chapter is dedicated to showing you how you can code up some of the popular and useful information retrieval algorithms using F# and then use them in your problem domain.
