We assume that we have a probability density function f defined on the feature space (e.g. a normalized density of a data set). For a given point $$\varvec{w}$$ of concept space, we give explicitly a set of points in feature space that are mapped onto $$\varvec{w}$$ and we give a formula for a reverse mapping to the feature space which results in minimum mean squared error, with respect to density f, of the operation of mapping a point of feature space into the concept space and back. We characterize the circumstances under which points can be mapped back into the feature space unambiguously and provide a formula for the inverse mapping. %G English %Z TC 8 %2 https://inria.hal.science/hal-01637496/document %2 https://inria.hal.science/hal-01637496/file/419526_1_En_7_Chapter.pdf %L hal-01637496 %U https://inria.hal.science/hal-01637496 %~ SHS %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC8 %~ IFIP-CISIM %~ IFIP-LNCS-9842
