Researchers have introduced DMVM, a novel framework for decentralized multi-task dataset valuation. This method bypasses the need for retraining or direct data sharing by utilizing task arithmetic to infer dataset contributions from model combinations. DMVM quantifies how models trained on different datasets combine in parameter space to determine each dataset's marginal utility across multiple tasks, offering a scalable and efficient valuation process suitable for decentralized environments with privacy constraints. The framework includes a secure aggregation protocol for collaborative valuation without revealing individual model parameters or private data, and its effectiveness has been demonstrated through experiments in computer vision and natural language processing.
