Congrats to my co-authors @RachaelSim2 @YvonneFan12 @snoidetx @michael_xinyi @pjaillet!!! @icmlconf #ICML2026 #CollaborativeLearning involves training high-quality models using datasets from a number of sources. To incentivize sources to share data, existing #DataValuation methods fairly reward each source based on its data submitted as is. However, as these methods do not verify nor incentivize data truthfulness, the sources can manipulate their data (e.g., by submitting duplicated or noisy data) to artificially increase their valuations and rewards or prevent others from benefiting. This paper presents the first mechanism that provably ensures (F) collaborative #fairness and incentivizes (T) #truthfulness at equilibrium for Bayesian models. Our mechanism combines semivalues (e.g., #ShapleyValue), which ensure fairness, and a truthful data valuation function (DVF) based on a validation set that is unknown to the sources. As semivalues are influenced by others' data, we introduce an additional condition to prove that a source can maximize its expected data values in coalitions and semivalues by submitting a dataset that captures its true knowledge. Additionally, we discuss the implications and suitable relaxations of (F) and (T) when the mediator has a limited budget for rewards or lacks a validation set. Our theoretical findings are validated on synthetic and real-world datasets.

🚨🤔 How can we reduce the cost of cooperative game-based #DataValuation without retraining a model for every coalition? 💡🔍 DUPRE — Data Utility PREdiction for efficient data valuation — fits a #GaussianProcess predictor with a sliced Wasserstein kernel to estimate each coalition’s utility from just a handful of evaluated subsets. 👩‍💻👨‍💻 nguyen pham @RachaelSim2 @qphong see kiong ng @bryanklow 🚀 Paper: arxiv.org/abs/2502.16152 📌 Catch DUPRE @AAMASconf #AAMAS2025 — 22 May (afternoon) 🗣Oral in Ambassador Ballroom • Salon 3 (3 pm) 🖼 Poster #1303 in Ontario Exhibit Hall (3rd floor) ( p.m.) Drop by to see how DUPRE: ✅ exploits owners’ data similarity to predict utilities ✅ plugs into any cooperative game theory techniques ✅ delivers uncertainty-aware data valuations
