Embodiment Construction

[0037] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] Cross-frequency coupling (CFC) is widely used to characterize oscillation coupling between different bands, with a variety of modes, such as amplitude coupling (AAC), phase coupling (PPC), phase frequency coupling (PFC), and phase-frequency coupling (PAC) Wait, it is closely related to human cognition and behavior. Among them, the phase-wage coupling (PAC) is defined as the modulation capability of the low frequency phase on its high frequency amplitude. The low frequency phase reflects the activity of local neurons, high-frequency amplitude reflects the general state of synaptic activities in the group or the selective excitability of neural networks connected. Since the proposal, PAC has become a popular method of various research, closely related to memory consolidation, attention control and spasm, and plays an important role in neurological activities.

[0039] The first step of quantifying the PAC is also the ...

Abstract

The invention belongs to the crossing field of cognitive neuroscience and information technology, and particularly relates to an emotion recognition method, device and platform based on variational phase amplitude coupling and a computer readable storage medium. The emotion recognition method based on variational phase-amplitude coupling comprises a data acquisition step, a preprocessing step, a variational mode decomposition step, a phase-amplitude coupling analysis step, a significance test step and a recognition step. The invention discloses an emotion recognition device based on variational phase-amplitude coupling. The emotion recognition device comprises a data acquisition module, a preprocessing module, a variational mode decomposition module, a phase-amplitude coupling analysis module, a significance test module and a recognition module. According to the invention, the phase-amplitude coupling value which is tested to be significant is averagely distributed to the dual-frequency coupling map, so that the emotion of the testee is identified. According to the method, the electroencephalogram signal characteristics in different emotional states can be effectively extracted, and the accuracy and reliability of emotion recognition are improved.

Description

Technical field [0001] The present invention belongs to the field of cognitive neuroscience and information technology, and more particularly to an emotional identification method, apparatus, platform, and computer readable storage medium based on variational phase-based coupling. Background technique [0002] Emotion is an attitude experience of objective things and corresponding behavioral reactions, efficient, accurate distinguishing emotions, which will have a huge impact on actual production and life. For example, in patients with psychological disease or expression disorders, it helps to diagnose the condition and to help patients to relieve pain; in classroom teaching, according to the mood of the audience, take different teaching methods, can Increase the interaction of the classroom and improve the efficiency of teaching. [0003] Currently, there are a variety of emotional identification methods to identify and classify emotions, and common methods include identificatio...
