Abstract

# Replication Package for L2R Models Evaluation This repository contains all necessary resources to replicate the experiments described in our evaluation of Learning-to-Rank (L2R) models applied to grayscale-based code change analysis. ## OverviewWe evaluate three L2R models for ranking modified lines of code based on their relevance:**Model 1**: Baseline L2R model.**Model 2**: Uses expert-annotated data.**Model 3**: Fully automated grayscale-based annotation model. Model 3 automatically assigns labels to modified code lines based on grayscale heuristics, and its ranking results are generated similarly to Model 2. ### Results Summary | Model | MAP | MRR | ACC@1 || Model 1 | 0.408 | 0.659 | 0.521 || Model 2 | 0.429 | 0.705 | 0.608 || Model 3 | 0.427 | 0.704 | 0.608 | These results suggest that the automatic grayscale-based Model 3 achieves comparable performance to expert-labeled Model 2, at a much lower cost. ## How to Replicate All files required to replicate the experiments (datasets, configuration, and scripts) are available at: 👉 https://doi.org/10.6084/m9.figshare.24448888
