Meta-Cal: Well-controlled Post-hoc Calibration by Ranking

Xingchen Ma, Matthew B. Blaschko

In many applications, it is desirable that a classifier not only makes accurate predictions, but also outputs calibrated posterior probabilities. However, many existing classifiers…

Additive Tree-Structured Conditional Parameter Spaces in Bayesian Optimization: A Novel Covariance Function and a Fast Implementation

Xingchen Ma, Matthew B. Blaschko

Bayesian optimization (BO) is a sample-efficient global optimization algorithm for black-box functions which are expensive to evaluate. Existing literature on model based optimizat…
