Abstract: The disclosure provides a method for enriching epileptiform discharges and predicting SOZ during epilepsy interictal period, including the following steps: obtaining stereotactic electroencephalogaphy signals of patient during the epilepsy interictal period; preprocessing the stereotactic electroencephalogaphy signals to obtain processed stereotactic electroencephalogaphy signals; dividing the processed stereotactic electroencephalogaphy signals into a training set and a test set, dividing the training set into a plurality of signal segments by using a sliding window, and performing a self-supervised reconstruction training on the signal segments based on a Transformer encoder model to obtain a trained Transformer encoder model; inputting the test set into the trained Transformer encoder model, obtaining reconstructed values of each of the signal segments, comparing the reconstructed values of each of the signal segments with values of the stereotactic electroencephalogaphy signals to obtain deviation values of each of the signal segments from the background signals.
