Last updated: 1/9/2025

Description

This paper presents a novel approach to EEG (Electroencephalography) signal analysis using a Convolutional Recurrent Attention Model (CRAM). The method focuses on subject-independent EEG analysis, aiming to enhance the accuracy and generalizability of EEG signal interpretation. The CRAM integrates convolutional neural networks (CNNs) for feature extraction with recurrent neural networks (RNNs) to capture temporal dynamics, and an attention mechanism to prioritize relevant features in EEG signals.
