Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Reproducibility Variable Result LLM Response
Research Type Experimental Through comprehensive synthetic and semi-synthetic experiments, we demonstrate that CLEXNET outperforms existing acceptance models in generalization, calibration, and predictive accuracy offering a practical and robust improvement for policy simulators. More broadly, our approach opens a new direction in counterfactual machine learning by operationalizing contrastive human feedback in high-stakes, observational settings like organ transplantation.

Pseudocode Yes Algorithm 1: CLEXNET : single instance training step with explanation-guided augmented loss
Open Source Code Yes All code, synthetic generators and an implementation of CLEXNET are made public to facilitate independent assessment: https://github.com/Alessandro Marchese/Clex Net.
Open Datasets Yes For the semi-synthetic evaluation, we use UNOS-PTR [15] liver offers recorded between 2021 and 2024. This data consists of approximately 1.1M offers made between 24k unique organs and 46k unique patients.
Dataset Splits Yes Dobs is then split further into Dtrain, which is used to train the models, and Dtest, which is used to test the models on observational data. We allocate 70% of Dobs to Dtrain, 15% for a validation set and 15% to Dtest (stratified by Y).
Hardware Specification Yes Experiments ran on a 13th Gen Intel(R) Core(TM) i9-13900HX processor with 32GB RAM.
Software Dependencies No The paper mentions software components like PyTorch implicitly through the neural network architecture, but it does not specify any software dependencies with their corresponding version numbers.
