Unsupervised Learning for Algorithmic Trading
Enable algorithms to find structure in unlabeled data and engineer features using Python
Traders and investors are deluged with unending streams of financial data with very low signal-to-noise ratios. Often traders don’t know what features or patterns they should be looking for in these voluminous streams of noisy data, especially if market conditions are unfamiliar or have changed substantially. These problems make data processing and engineering models for algorithmic trading extremely challenging, even for experts.
To tackle these challenges, traders and investors are increasingly enlisting the help of advanced machine learning algorithms and techniques that don’t require direct supervision of the learning process. These unsupervised learning algorithms not only help traders discover and visualize the structure of unlabeled financial data but also help them get rid of redundant features in their models, greatly enhancing the efficiency and effectiveness of their algorithmic trading systems.
Expert Deepak Kanungo takes you through the ins and outs of unsupervised machine learning in algorithmic trading and investing. You’ll examine fundamental concepts, the pros and cons of using unsupervised learning, how to use algorithms like k-means clustering and principal component analysis (PCA), and more. Join in to learn how to use unsupervised learning to engineer new features in your trading models and redesign your investment portfolio to reduce correlations in asset price returns.
What you'll learn-and how you can apply it
