Machine learning met asset pricing in earnest when tree ensembles and neural nets were set loose on the cross-section of returns, and the field has been arguing about what they found ever since. The branches: predicting the cross-section, compressing it into latent factors, mining text for pricing information, and the growing literature on whether any of it survives honest validation. Trial counts matter more here than anywhere — read with the deflated-Sharpe lens.
