Safe Bayesian Optimization for Uncertain Correlation Matrices in Linear Models of Co-Regionalization
arXiv:2605.13302v2 Announce Type: replace Abstract: This paper extends safety guarantees for multi-task Bayesian optimization with uncertain co-regionalization matrices from intrinsic co-regionalization models to linear models of co-regionalization. The latter allows for more flexible modeling of the inter-task correlations by composing multiple features. We derive uniform error bounds for vector-valued functions sampled from a Gaussian process with a linear model of co-regionalization kernel. Furthermore, we show the potential performance gains of linear models of co-regionalization in a nume
