PROFILE

Alexander Lam

Developed and integrated a Bradley-Terry subjective evaluation framework within the thunlp/SIR-Bench repository, enabling robust pairwise model comparisons across datasets such as AlpacaEval, CompassArena, WildBench, and Arena Hard. Leveraged Python and statistical modeling to implement scalable evaluation workflows, including new configuration files for both single-turn and multi-turn scenarios. Enhanced benchmarking fidelity by introducing features like predicted win rate reporting and a toggle between win rates and Elo ratings, supporting more actionable model selection. The work emphasized configuration management, data analysis, and reproducibility, resulting in a data-driven evaluation process that aligns benchmarking with business needs and reduces ambiguity in competitive tasks.
