Navigating the Factor Zoo

This book delivers a rigorous and stimulating discussion of fundamental questions. What does a human know that a machine learning algorithm cannot possibly know and vice versa? When does a serious investor know enough to act and when does the irreducible uncertainty lead to caution? This book offers a deeply insightful window into the modern frontier, and how to think about balancing sophisticated algorithms with practical challenges at the edges.
