AWhat changed
Fits lower and upper conditional quantiles on proper training data, then uses held-out signed interval errors to conformalize variable-width regression intervals.
Scientific scope
Fits lower and upper conditional quantiles on proper training data, then uses held-out signed interval errors to conformalize variable-width regression intervals. Finite-sample guarantee is marginal under exchangeability, not exact coverage at each covariate or arbitrary distribution drift. Quantile regression and conformal prediction are inherited; interval efficiency depends on the fitted quantiles and sample split.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
