Background:

Motor imagery electroencephalography (EEG) decoding is crucial for brain-computer interface (BCI) systems.
Existing decoding methods struggle with class-independent information in EEG signals, limiting accuracy.

Purpose of the Study:

To propose a novel motor imagery EEG decoding method that overcomes interference from class-independent information.
To improve the decoding accuracy of BCI systems.

Main Methods:

A feature separation network based on adversarial learning (FSNAL) was designed.
FSNAL separates class-related and class-independent features from raw EEG data.
Motor imagery decoding is performed using only the extracted class-related features.

Main Results:

The proposed method was validated on two public EEG datasets (BCI competition IV 2a and 2b).
Experimental results demonstrated superior performance compared to state-of-the-art methods.
The motor imagery EEG decoding method significantly outperformed all compared approaches.

Conclusions:

The developed motor imagery EEG decoding method effectively mitigates interference from class-independent features.
This approach holds significant potential for enhancing the performance of future motor imagery BCI systems.
