Multinomial Logit - Model - Introduction
... predictive model that is broken down into a series of submodels where the prediction of a given submodel is used as the input of another submodel, and that prediction is in turn used as the input into a ... If each submodel has 90% accuracy in its predictions, and there are five submodels in series, then the overall model has only.95 = 59% accuracy ... If each submodel has 80% accuracy, then overall accuracy drops to.85 = 33% accuracy ...
Substructure - Submodel
... In model theory, given a structure M which is a model of a theory T, a submodel of M in a narrower sense is a substructure of M which is also a model of T ... of abelian groups in the signature (+, 0), then the submodels of the group of integers (Z, +, 0) are the substructures which are also groups ... Thus the natural numbers (N, +, 0) form a substructure of (Z, +, 0) which is not a submodel, while the even numbers (2Z, +, 0) form a submodel which is (a group but) not a subgroup ...
