Reliably characterizing the full conditional distribution of a multivariate response variable given a set of covariates is crucial for trustworthy decision-making.
Standard recalibration methods are limited to univariate settings, and conformal prediction techniques do not provide a full probability density function for multivariate prediction regions.
A novel latent recalibration (LR) method is introduced, which assesses probabilistic calibration in the latent space of a conditional normalizing flow and provides recalibrated distribution with an explicit multivariate density function.
Extensive experiments on tabular and image datasets demonstrate that LR consistently improves latent calibration error and the negative log-likelihood of the recalibrated models.
