Title:
ELECTROENCEPHALOGRAM SIGNAL CLASSIFICATION METHOD AND APPARATUS, AND DEVICE, STORAGE MEDIUM AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/179548
Kind Code:
A1
Abstract:
An electroencephalogram signal classification method and apparatus, and a device, a storage medium and a program product, which relate to the technical field of signal processing. The method comprises: acquiring a first electroencephalogram signal (201); acquiring respective time-frequency feature maps of at least two electrode signals in the first electroencephalogram signal (202); performing feature extraction on the basis of the respective time-frequency feature maps of the at least two electrode signals, so as to obtain a first extracted-feature map (203); performing attention-mechanism-based weighting processing on the first extracted-feature map, so as to acquire an attention feature map (204); and on the basis of the attention feature map, acquiring a motor imagery type of the first electroencephalogram signal (205).
