Abstract

The invention provides a hand tremor signal and audio signal classification method based on evolutionary fuzzy rules, which can improve the interpretability of the evolutionary fuzzy classifier. The method includes: obtaining characteristic sample points representing Parkinson's disease and normal people according to the collected physiological data, the physiological data being expressed as time series information; constructing an evolutionary fuzzy classifier based on the mined evolutionary fuzzy rules, and Train the evolutionary fuzzy classifier according to the obtained characteristic sample points representing Parkinson's disease and normal people, and determine the classification threshold of the evolutionary fuzzy classifier; obtain new testers according to the constructed evolutionary fuzzy classifier The number of sample points belonging to Parkinson's disease characteristics in the physiological data. The invention is applicable to the technical field of biomedicine.

Description

technical field

[0001] The invention relates to the technical field of biomedicine, in particular to a method for classifying hand tremor signals and audio signals based on evolutionary fuzzy rules. Background technique

[0002] Parkinson's disease is a neurological dysfunction disease that seriously threatens the health and quality of life of middle-aged and elderly people. Clinically, the main symptoms are static tremor, slow movement, stiffness, unstable posture, and language barriers. Now the incidence is increasing year by year. High, very common, there is no cure, only control, so early diagnosis is very critical. Among the various manifestations of Parkinson's disease, language barrier is one of the typical symptoms of early Parkinson's disease, and about 90% of Parkinson's patients will have some degree of language barrier.

[0003] In the prior art, for example, the speech signal of the tester is classified based on the support vector machine, and the diagnostic ac...
