Experiments with some algorithms that find central solutions for pattern classification

In two-class pattern recognition, it is a standard technique to have an algorithm finding hyperplanes which separates the two classes in a linearly separable training set. The traditional methods find a hyperplane which separates …

Logic and semantic networks

An extended form of semantic network is defined, which can be regarded as a syntactic variant of the clausal form of logic. By virtue of its relationship with logic, the extended semantic network is provided with a precise semantics …

The use of normal multiplication tables for information storage and retrieval
