Machine Learning For Finance

1. Regression Based Machine Learning for Algorithmic Trading

Machine Learning for Finance, Algorithmic Trading and Investing Slides

These set of slides explained the current asset management environment and the advanced of technology on asset management. Categories of Machine and Deep Learning are explained. A brief introduction on linear regression and associated assumptions are covered. Stylized statistical properties of financial time series and asset returns are presented highlighting the challenges.

To ease learners to understand machine learning, linear regression has been used as the conduit. Firstly, the shortcoming of linear regression is highlighted. We then follow by the steps of model building and covering concepts such as hyperparameters, cross-validation, model validation, bias-variance tradeoff. The 6 stages of professional quant strategy is also covered to provide some perspective on where machine learning fits in.

2. Classification Based Machine Learning for Algorithmic Trading

This portion is under active development at the moment. I have uploaded some of my codes and backtesting results. A common use of classification ML is to predict the next day's result. You can find some examples here. Some of the ML classification methods were capable of achieving prediction accuracy of pver 60%. Does that translate directly to returns and out-performance over simple buy-and-hold strategy? Check out the backtesting tearsheets for the answer.
