KAS: A Kernel Alignment-Based Sampling Probability Approach for Medical Data Valuation
Published 2025-01-01“…This paper introduces Kernel-Aligned Sampling (KAS), a dual-mechanism framework that innovates through: 1) A kernel-aligned sampling probability strategy that aligns valuation distributions with feature-space similarity to stabilize Shapley approximations and resolve the speed-accuracy dilemma; 2) A prior-guided data refinement mechanism that leverages domain knowledge to implicitly decompose data into signal and noise components, mitigating misattribution of noisy or incomplete data as low-value; 3) Experiments on 10 datasets and 4 baselines demonstrate that KAS outperforms baseline methods by 5.7%-8.8% in high-value data ablation tests and achieves an average improvement of 4.3% in noisy data detection accuracy compared to the second-best method.…”
