Embodiment Construction
[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0057] Such as figure 1 and 2 As shown, the general implementation steps of the multi-channel joint detection method for spike discharge have been introduced in detail in the content of the invention, that is, the technical solution of the present invention mainly includes the following steps:
[0058] Step 1. Filter the input raw multi-lead EEG and eliminate artifacts caused by physiological activities such as ECG, chewing and swallowing. The processed signal is first segmented in the time domain according to the duration characteristics of the detected target waveform, and the signal is converted into a recognition form for subsequent steps.
[0059] Step 2. The data of each channel in the segmented signal is subjected to feature extraction through a long-short-term memory neural network, and feature fusion is performed through an adaptiv...
