Regression Conformal Prediction with Nearest Neighbours

no code implementations16 Jan 2014 Harris Papadopoulos, Vladimir Vovk, Alex Gammerman

A comparison of the predictive regions produced by our measures with those of the typical regression measure suggests that a major improvement in terms of predictive region tightness is achieved by the new measures.
