Abstract

The invention discloses a microwave breast tumor classification method based on deep learning, which is used for solving the problems of breast tumor positioning and soft classification redesignation by constructing a domain adversarial neural network, and redefining a loss function. Compared with a real-value multilayer perceptron, the domain adversarial neural network only uses data of 250 target domains to enable the neural network to adapt to a new domain with remarkably different data distribution, and a reasonable result is obtained for unknown data in a laboratory experiment.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a microwave breast tumor classification method based on deep learning. Background technique [0002] In breast tumor detection, determining tumor size and location is critical for preventive diagnosis. Therefore, a fast and accurate method for tumor localization and size estimation is very important. While magnetic resonance imaging (MRI) and computed tomography (CT) serve contemporary medical needs, they are expensive, bulky, and heavy, making them unsuitable for early diagnosis of breast tumors. [0003] As a supplement to existing imaging methods, electromagnetic imaging technology has great development prospects. Electromagnetic imaging uses an antenna array surrounding the breast to measure transmission and reflection coefficients, and these complex-valued parameters can be processed using various techniques, such as tomography and radar-based techniques, ...
