Electroencephalogram sleep staging method and device, electronic equipment and storage medium

The invention relates to an electroencephalogram sleep staging method and device, electronic equipment and a storage medium. The electroencephalogram sleep staging method comprises the following steps: acquiring electroencephalogram signals to be classified; inputting the electroencephalogram signal into a trained feature extraction network to obtain a feature vector corresponding to the electroencephalogram signal; inputting the feature vector into a trained classifier to obtain a sleep stage classification result corresponding to the electroencephalogram signal; wherein the classifier is a prototype network improved based on a meta learning algorithm. According to the electroencephalogram sleep staging method, aiming at the problem that the number of patient samples is small, information of non-target domain data can be fully utilized, and the information is migrated on a target domain. And only a small amount of sample data is needed for each category. 本发明涉及一种脑电睡眠分期方法、装置、电子设备及存储介质。本发明所述的脑电睡眠分期方法包括：获取待分类的脑电
