Cross-device electroencephalogram data alignment method and device, equipment and storage medium

The invention discloses a cross-device electroencephalogram data alignment method and device, equipment and a storage medium. The method comprises the following steps: inputting source domain electroencephalogram data into a source domain data processing module of a pre-constructed network model, and performing data filtering processing on the source domain electroencephalogram data by the source domain data processing module to obtain source domain filtering data output by the source domain data processing module; inputting the target domain electroencephalogram data into a target domain data processing module of a pre-constructed network model, and performing data filtering processing on the target domain electroencephalogram data by the target domain data processing module to obtain target domain filtering data output by the target domain data processing module; determining a target loss value based on a preset spatial distribution difference measurement mode according to the source domain filtering data a
