Brain wave analysis method

Abstract

The invention provides a brain wave analysis method. The method uses classical time-frequency domain analysis and principal component analysis methods to solve the problem of electroencephalographic feature extraction, successfully extracts time-frequency domain parameters closely related to the tension, fatigue and relaxation of human bodies, maps the time-frequency domain parameters into principal component space, and uses a support vector machine to efficiently analyze non-linear relation in the principal component space so as to improve the accuracy and validity of interpretation.

Description

technical field

[0001] The invention relates to human health engineering, neurophysiology, biomedical digital signal processing technology, pattern extraction and pattern classification, software engineering, and in particular to a brain wave analysis method. Background technique

[0002] In addition to the prosperity of the city, the rapid urban rhythm and fierce market competition have brought us more and more work pressure on white-collar workers. As a result, more and more people are in a sub-health state. . The main symptoms of sub-health should include fatigue, insomnia, headache, muscle and joint pain, frequent colds, chest tightness, shortness of breath, heart palpitations, loss of appetite and other physical manifestations; depression, anxiety, fear, apathy, loneliness, jealousy, lack of energy, Psychological manifestations such as depression; and social adaptation manifestations such as inability to undertake corresponding social obligations and responsibilities w...
