Attributes: Selective Learning and Influence
summary
Characterizes which K attributes to sample when attribute realizations follow a Gaussian process and two players disagree on attribute weights, using Brownian, Ornstein–Uhlenbeck and squared‑exponential kernels; shows optimal sampling is governed by two sufficient statistics (principal’s posterior variance and the covariance between agent value and principal decision) and by a nearest-attribute property (Markov covariance). Under that property samples are mostly relevant (at most two idiosyncratic picks, rest common) and optimization breaks into k‑local problems; non‑Markov kernels can make sampling irrelevant attributes optimal when correlation is extreme.
