DFF: Decision-Focused Fine-Tuning for Smarter Predict-Then-Optimize with Limited Data

AAAI 2025technical

Decision-focused learning (DFL) offers an end-to-end approach to the predict-then-optimize (PO) framework by training predictive models directly on decision loss (DL), enhancing decision-making performance within PO contexts. However, the implementation of DFL poses distinct challenges. Primarily, D…

OAM: An Option-Action Reinforcement Learning Framework for Universal Multi-Intersection Control

AAAI 2022technical

Efficient traffic signal control is an important means to alleviate urban traffic congestion. Reinforcement learning (RL) has shown great potentials in devising optimal signal plans that can adapt to dynamic traffic congestion. However, several challenges still need to be overcome. Firstly, a paradi…
