Evaluating the Effectiveness of Index-Based Treatment Allocation

We show how a connection to the 'individualized treatment rules' literature in statistics to create asymptotically valid confidence intervals for RCTs that measure the quality of 'clever' intervention policies.

Group Fairness in Predict-Then-Optimize Settings for Restless Bandits

We show how decision-focused learning can improve the fairness-accuracy tradeoff in algorithmic decision-making using a case study on a real-world domain.

Efficient Public Health Intervention Planning Using Decomposition-Based Decision-Focused Learning

We propose an efficient way to implement decision-focused learning for the kinds of RMABs used for intervention planning in public health.

Learning Loss Functions for Predict-then-Optimize

A blog post about the predict-then-optimize paradigm for algorithmic decision-making, and how we can view it as inducing a task-specific loss function in supervised machine learning.

Leaving the Nest: Going Beyond Local Loss Functions for Predict-Then-Optimize

We propose two new innovations to help improve the learning of task-specific loss functions.

Decision-Focused Learning without Decision-Making: Learning Locally Optimized Decision Losses

We learn task-specific loss functions that, when trained on, allow a predictive model to make better predictions for the given task.
