This repository contains the code for the papers:
- "Predict-then-optimize or predict-and-optimize? An empirical evaluation of cost-sensitive learning strategies" Information Sciences (2022).
- "A new perspective on classification: Optimally allocating limited resources to uncertain tasks" Decision Support Systems (2023).
For (1), an experiment is conducted by running the experiments/overview.py file where settings, data set, methodologies, and evaluators can be chosen.
For (2), experiments can similarly be replicated using experiments/overview_ranking.py.
Due to size limitations, not all data is provided in this repository. Data sets can be found online at the following links:
