Machine Learning for Finance

4.1 (59)
By: James Le , Jannes Klaas

Overview of this book

Machine Learning for Finance explores new advances in machine learning and shows how they can be applied across the financial sector, including insurance, transactions, and lending. This book explains the concepts and algorithms behind the main machine learning techniques and provides example Python code for implementing the models yourself. The book is based on Jannes Klaas’ experience of running machine learning training courses for financial professionals. Rather than providing ready-made financial algorithms, the book focuses on advanced machine learning concepts and ideas that can be applied in a wide variety of ways. The book systematically explains how machine learning works on structured data, text, images, and time series. You'll cover generative adversarial learning, reinforcement learning, debugging, and launching machine learning products. Later chapters will discuss how to fight bias in machine learning. The book ends with an exploration of Bayesian inference and probabilistic programming.

Rule-based matching


Before deep learning and statistical modeling took over, NLP was all about rules. That's not to say that rule-based systems are dead! They are often easy to set up and perform very well when it comes to doing simple tasks.

Imagine you wanted to find all mentions of Google in a text. Would you really train a neural network-based named entity recognizer? If you did, you would have to run all of the text through the neural network and then look for Google in the entity texts. Alternatively, would you rather just search for text that exactly matches Google with a classic search algorithm? Well, we're in luck, as spaCy comes with an easy-to-use, rule-based matcher that allows us to do just that.

Before we start this section, we first must make sure that we reload the English language model and import the matcher. This is a very simple task that can be done by running the following code:

import spacy
from spacy.matcher import Matcher

nlp = spacy.load('en')

The matcher searches...
