Abstract

The invention relates to the technical field of pattern recognition, and discloses an identifiable geometry preserving adaptive graph embedding method, a device, equipment and a medium, the method comprises the following steps: obtaining a high-dimensional data set, the high-dimensional data set comprising a training set and a test set, the training set further comprising corresponding category information; constructing an identifiable geometry preserving adaptive graph embedding model; inputting the training set into the identifiable geometry preserving adaptive graph embedding model, and solving to obtain a weight matrix and a projection matrix, wherein the weight matrix is used for optimizing the projection matrix; and projecting the test set through the projection matrix to obtain low-dimensional representation. The method solves the problem that the structure information reflected by an existing graph embedding method is unsuitable for data, unreliable or insufficient due to the fact that the existing graph embedding method cannot adapt to different data samples in a partial graph composition mode.

Description

technical field [0001] The present invention relates to the technical field of pattern recognition, and specifically refers to a method, device, equipment and medium for embedding an identifiable geometry-preserving adaptive graph. Background technique [0002] In recent years, pattern recognition has been applied to text, voice, fingerprint, remote sensing, medical diagnosis and other aspects. Massive data with high-dimensional features makes it difficult for researchers to directly mine the internal relationships and laws of the data. These data are large in quantity and high in dimension, which not only wastes a lot of storage space, but also brings unnecessary calculations, which brings many challenges to the research of related application fields. Therefore, extracting key features from the redundant features of high-dimensional data has become an important research topic in various fields such as pattern recognition, artificial intelligence, and computer vision.
