Machine Learning for Cross-Sectional Factor Strategies and AI Factor Mining

Summary

The document outlines a training program on cross-sectional multi-factor strategies, also described as alpha strategies. Its curriculum spans factor data preparation, supervised learning, model evaluation and interpretation, portfolio construction, and strategy backtesting. It names linear, ensemble, and neural network model families, and describes applying these approaches to equities and leveraged long-short portfolios in markets such as futures and fixed income.

A new topic is using large language models and AI agents to extract factor ideas from research reports, turn them into formulas, and evaluate them through an automated research process. The document gives a course syllabus rather than empirical results or a tested strategy. It also cautions that the work requires substantial knowledge of factor data, computing, and financial theory, so the course is not aimed at beginners. The described methods and workflows are educational topics, not evidence of profitable performance.

Key ideas

• Cross-sectional factor strategies rank assets using features and machine learning predictions.
• The curriculum covers data preparation, model training, evaluation, interpretation, and portfolio construction.
• It includes models ranging from linear regression to tree ensembles and neural networks.
• AI tools may help extract candidate factor logic from research reports and support its evaluation.
• The document provides a course outline, not performance evidence, and says the subject is advanced.
