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…

Long-Term Individual Causal Effect Estimation via Identifiable Latent Representation Learning

IJCAI 2025

Estimating long-term causal effects by combining long-term observational and short-term experimental data is a crucial but challenging problem in many real-world scenarios. In existing methods, several ideal assumptions, e.g. latent unconfoundedness assumption or additive equi-confounding bias assum

Contrastive Balancing Representation Learning for Heterogeneous Dose-Response Curves Estimation

AAAI 2024technical

Estimating the individuals' potential response to varying treatment doses is crucial for decision-making in areas such as precision medicine and management science. Most recent studies predict counterfactual outcomes by learning a covariate representation that is independent of the treatment variabl…
