Problems solved by technology

[0003] Traditional detection methods rely on manual visual annotation of spindle activity in sleep data. Although manual assessment of sleep spindles has been standardized by AASM, manual detection is still a time-consuming, labor-intensive, and costly task. In addition, if There may be disagreements when multiple experts judge together

Abstract

The invention relates to a method and device for detecting sleep spindle waves, electronic equipment and a storage medium. The method for detecting the sleep spindle wave comprises the following steps: acquiring sleep data to be detected, wherein the sleep data comprises a plurality of EEG (electroencephalogram) signals; filtering the sleep data to obtain an EEG (electroencephalogram) signal with a specific frequency; performing candidate wave identification processing on the EEG signals with the specific frequency by adopting an MP algorithm to obtain candidate waves of sleep spindle waves; extracting features of the candidate waves, and performing normalization processing on the features to obtain feature vectors of the candidate waves; and inputting the feature vectors into a trained SVM classifier to obtain a classification result whether each candidate wave is a sleep spindle wave or not. According to the method for detecting the sleep spindle waves, the reliability and objectivity of accurate detection of spindle movement are improved, and the limitation of manual detection of spindle events is made up.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to a method, device, electronic device and storage medium for detecting sleep spindle waves. Background technique [0002] The sleep spindle is generated in the thalamocortical system and is one of the most important sleep events in the microstructure of sleep. The American Academy of Sleep Medicine (AASM) believes that the sleep spindle occurs in the NREM stage of non-rapid eye movement sleep and is a sinusoidal EEG signal phenomenon with a duration of at least 0.5s and a frequency distribution between 11-16Hz. . Throughout life, the density, number, and amplitude of spindle events have been shown to correlate with general cognitive performance, sleep quality, and learning and memory. Experts from the research center of Stockholm University, Sweden, said: "Spindle waves can effectively inhibit the interference of external stimuli on sleep. The thalamus p...
