We introduce a new methodology, called SVORIM+, for utilizing privileged information of the training examples, unavailable in the test regime, to improve generalization performance in ordinal regression. The privileged information is incorporated during the training by modelling the slacks through correcting functions for each of the parallel hyperplanes separating the ordered classes. The expe...

Improving green total factor productivity (GTFP) is the key for China’s mineral resources industry to get out of dilemma resource depletion and environmental degradation. The Super Slacks-Based Measure (Super-SBM) model with undesirable output used calculate GTFP between 2004 2019, space–time correlation threshold quantitatively determined by semivariogram. On this basis, spatial weight matrix ...
