Machine Learning for Finance

By: 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.

An introductory guide to spaCy


spaCy is a library for advanced NLP. The library, which is pretty fast to run, also comes with a range of useful tools and pretrained models that make NLP easier and more reliable. If you've installed Kaggle, you won't need to download spaCy, as it comes preinstalled with all the models.

To use spaCy locally, you will need to install the library and download its pretrained models separately.

To install the library, we simply need to run the following command:

$ pip install -U spacy
$ python -m spacy download en

Note

Note: This chapter makes use of the English language models, but more are available. Most features are available in English, German, Spanish, Portuguese, French, Italian, and Dutch. Entity recognition is available for many more languages through the multi-language model.

The core of spaCy is made up of the Doc and Vocab classes. A Doc instance contains one document, including its text, tokenized version, and recognized entities. The Vocab class, meanwhile...
