FEATURE GENERATION BASED ON EIGENFUNCTIONS OF THE SCHRÖDINGER OPERATOR

摘要

A method for generating a feature (330) associated with input data includes receiving (900) the input data (300); projecting (902) the input data (300) with a set of square functions ψ²_nh of the Schrödinger operator; selecting (904) the feature (330) to be a number of the negative eigenvalues λ_nh of the Schrödinger operator; and classifying (906) the input data (300) based on the feature (330).
