Embodiment Construction
[0034] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation plan and a specific operation process.
[0035] Surface Electromyographic (sEMG) is the temporal and spatial superposition of motor unit action potentials (MUAP) in numerous muscle fibers. Studying the coupling information between sEMG signals can not only reflect the different motor control strategies of the motor central nervous system and the motor function status of muscles, but also realize the decoding of EMG signals and explore the inner motor function control mechanism.
[0036] According to the principle of Copula entropy equivalence, the present invention extends the traditional two-dimensional transfer entropy to high-dimensional situations, introduces the R-Vine Copula theory to measure the transfer entro...
