Embodiment Construction
[0032] Embodiments of the method of the present invention will be further described below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, it is a flow chart of automatic spike detection and peak location according to an embodiment of the present invention, which mainly includes the following steps.
[0034] Step 1: Data preprocessing.
[0035] This step preprocesses the input raw data of the magnetoencephalogram, filters the signal, removes artifacts, standardizes, and segments, so that the data can be better put into the deep learning network for training.
[0036] Such as figure 2Shown is the data preprocessing module, which performs the following preprocessing on the input magnetoencephalogram data, mainly including the following steps.
[0037] 1) Use 1-100Hz bandpass filter and 50Hz notch filter to remove low frequency, high frequency and power frequency noise on each channel.
[0038] 2) Use Independent Component Analysis (ICA) to ...
