[0136] 2. Different from the traditional method, the present invention innovatively adopts the framework based on two-stage deep transfer learning for the first time. In the field of computer vision for object recognition, two important theories have been proven: first, deeper features have a stronger abstraction ability for input images; second, high-level visual features can be derived from low-level features (points, line, surface, shadow, light and shade, etc.). Although high-level features often have different morphological structures and feature representations in different tasks, the low-level features that make up these features can often be shared in different models. But training a deeper network also means greater difficulties: (1) It is more difficult to effectively transfer the calculation results to the deep layer of the network to avoid problems such as gradient dispersion or gradient disappearance. (2) Even if the model can abstract low-level features very wel...

Abstract

A two-stage deep transfer learning traditional Chinese medicine tongue diagnosis model belongs to the technical field of traditional Chinese medicine auxiliary diagnosis and treatment. The method comprises the following steps: firstly, constructing a deep network based on a deep convolutional feature paradigm, fusing multi-scale features by using a pyramid strategy, and constructing deep abstractrepresentation of an input tongue image; then, designing two-stage deep transfer learning and obtaining the recognition capability of representative focus features in tongue image diagnosis in a targeted mode, thereby effectively solving the problem of data shortage, and reducing the training cost. On the basis, a focus examination cost function is designed, a deep migration model is trained, detection is carried out from different scales, an abnormal tongue image focus is marked, and the detection precision is improved. Finally, according to the examination result of the deep migration model,the process of combined use of multiple diagnostic methods of traditional Chinese medicine diagnosis and treatment is simulated, and real-time discrimination on abnormal tongue images is carried out,thereby improving the accuracy of diagnosis. The model designed by the invention can simulate the traditional Chinese medicine diagnosis theory, diagnose abnormal tongue images in real time, and provide clinical assistance and diagnosis and treatment suggestions for traditional Chinese medicine.

Description

technical field [0001] The invention belongs to the technical field of auxiliary diagnosis and treatment of traditional Chinese medicine, and relates to a two-stage deep transfer learning TCM tongue diagnosis model, which solves the problems of lack of data and low diagnostic accuracy faced by deep learning in the process of computerization of traditional Chinese medicine diagnosis and treatment methods. Background technique [0002] Traditional Chinese medicine is an important intangible cultural heritage of our country, which plays an important role in the treatment of chronic diseases and sudden diseases. With the common development of medicine and computer science, the modernization of traditional Chinese medicine has been paid more and more attention, and the standardization and computerization of traditional Chinese medicine diagnosis and treatment methods are imminent. It is of great practical significance to use advanced computer technology to simulate and reproduce ...
