Abstract

The invention discloses a blind field image sample classification method based on an over-limit latent feature model. The method adopts a cross-field data generation and augmentation strategy to efficiently reduce deviations between different data fields. Specifically, the ultra-limited latent feature model incorporates ELM and ELM‑AE (ELM-based autoencoder) into a unified optimization model, inherits the advantages of ELM and ELM‑AE, and can obtain Good image classification and image reconstruction effects, with image classification and image reconstruction capabilities, and can better reveal the potential relationship between original image data and advanced semantics, reduce information loss, and improve image classification accuracy. The invention solves the blind field adaptation problem by using the over-limit hidden feature model, integrates cross-field knowledge, effectively reduces the field deviation between data in different fields, and improves the classification accuracy of blind field data.

Description

technical field [0001] The present invention relates to the technical field of image classification and intelligent optimization, and more specifically, relates to a blind field image sample classification method based on an over-limit hidden feature model. Background technique [0002] In the field of computer vision, people often collect data from multiple fields, and there are differences in distribution. Traditional machine learning methods assume that the training set and the test set obey the same distribution. This assumption is often difficult to be satisfied in reality. Cross-domain image recognition is currently a research hotspot in the field of computer vision. Domain adaptation is to solve the problem of cross-domain image recognition. It is One of the research contents of transfer learning focuses on solving the problem that the feature space is consistent, the category space is consistent, and only the feature distribution is inconsistent. [0003] The basic ...
