Decoding Fine Motor Imagery with FingerNet: EEG Study

Core Concepts
The author introduces FingerNet, a specialized network for fine motor imagery classification, showcasing superior performance compared to baseline models. By optimizing network structure and addressing biased predictions, FingerNet aims to enhance motor imagery execution.
The study presents FingerNet, a network designed for fine motor imagery classification using EEG signals. It outperformed conventional models like EEGNet and DeepConvNet in classifying finger-tapping tasks. The weighted cross-entropy approach was employed to mitigate biased predictions, enhancing the model's accuracy. The research highlights the potential of FingerNet in improving motor imagery execution for both fine and gross motor tasks.
The average accuracy for FingerNet was 0.3049. EEGNet and DeepConvNet exhibited lower accuracies of 0.2196 and 0.2533, respectively. Weighted cross-entropy improved performance with values of 0.3120, 0.3102, and 0.3093.
