Interepileptic brain wave abnormal signal positioning method and device, equipment and medium

The invention discloses an interepileptic brain wave abnormal signal positioning method and device, equipment and a medium. The method comprises the following steps: acquiring brain wave signals, collected by a plurality of electrodes, of a target object in an epileptic seizure interval; performing independent component analysis on the brain wave signal acquired by each electrode, and removing an artifact signal in the brain wave signal acquired by each electrode to obtain an enhanced signal of each electrode; features of the enhanced signal of each electrode are extracted based on a plurality of wavelet bases, a plurality of feature sequences of each electrode are obtained, and part of the wavelet bases are waveform bases of abnormal brain wave shapes; analyzing an abnormal signal in the brain wave signal based on the feature sequence of each electrode, and determining the discharge time of the abnormal signal and a target electrode for collecting the abnormal signal; and positioning the abnormal signal base
