Local Probabilistic Model for Bayesian Classification: a Generalized Local Classification Model

no code implementations13 Dec 2018 Chengsheng Mao, Lijuan Lu, Bin Hu

In this paper, with the insight that the distribution in a local sample space should be simpler than that in the whole sample space, a local probabilistic model established for a local region is expected much simpler and can relax the fundamental assumptions that may not be true in the whole sample space.
