📖 Overview

Decision-Focused Learning (DFL) is an emerging paradigm that integrates machine learning with downstream optimization tasks. Unlike traditional two-stage approaches that minimize prediction error, DFL directly minimizes decision regret — the suboptimality of decisions made using predicted parameters.
