Feature analysis method, feature analysis apparatus, electronic device, program, and storage medium

摘要

The invention provides a characteristic analysis method, a device, an apparatus and a computer-readable storage medium, belonging to the technical field of data processing. The feature analysis methodcomprises the following steps: extracting feature extraction information from a feature template file; The data to be processed is aggregated into a plurality of feature groups according to the feature extraction information, and eigenvalues of each feature group are calculated; According to the feature extraction information and eigenvalues of each feature group, sample-level eigenvalues acrossthe feature groups are calculated, and eigenvalues of each feature group and the sample-level eigenvalues are spliced to obtain eigenvectors. The invention can carry out feature analysis on the data and extract the feature vector.
