This research introduces HoloCosm, a novel method for benchmark compression that simultaneously optimizes performance across multiple evaluation metrics rather than relying on single-metric heuristics. By addressing the weak correlation between different model assessment dimensions, the approach significantly reduces reconstruction error and ranking distortion while maintaining efficiency in evaluating large language models, multimodal systems, and agents.
HoloCosm: Beyond Single-Metric Benchmark Compression Across Multiple Metrics
arXiv:2610.26714v1 Announce Type: new Abstract: Benchmark compression reduces evaluation cost by selecting a small set of samples. Existing methods typically guide selection using a single metric, although benchmarks often assess models along multiple dimensions. We find that model rankings are often weakly correlated across metrics, indicating that different metrics capture distinct aspects of model performance. Samples selected for one metric do not reliably preserve scores and rankings on others when used for compressed evaluation. At 80\% compression, each of the five single-metric baselines yields higher reconstruction error than equal-size random sampling in over 70\% of cross-metric comparisons. To address this challenge, we present HoloCosm, which jointly minimizes normalized score-reconstruction error across source models and metrics while constraining ranking distortion. We evaluate HoloCosm across multiple compression rates on 15 language, multimodal, VLA, and agent benchmark configurations with 85 component metrics. With 80\% compression, HoloCosm outperforms Random, the strongest baseline overall: average NMAE drops by 35.3\% to 0.236, worst-component NMAE drops by 39.5\% to 0.330, and average Spearman correlation rises from 0.884 to 0.915. In addition, HoloCosm remains competitive with existing baselines in single-metric evaluation. We will release our code and experimental results.
