Abstract
This talk first gives an overview on the genesis of machine learning and AI and how statistical and computational methods have evolved with big data and become the foundation of modern machine learning and AI. It will also outline how ideas of trading modeling biases and variances have been developed into high-dimensional statistics and machine learning, with focus on deep learning models. We will highlight three applications: portfolio choices with text data via feature screening, predictability of the momentum and duration in high-frequency finance via several statistical machine learning methods, and sparse portfolio allocation and Sharpe ratio estimation.
