EEG Signal Analysis
EEG signal analysis aims to extract meaningful information from brain electrical activity, primarily for understanding cognitive processes and developing brain-computer interfaces (BCIs). Current research emphasizes improving the accuracy and robustness of EEG analysis by addressing challenges like noise and inter-subject variability, focusing on advanced deep learning architectures such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), transformers, and graph neural networks (GNNs), often incorporating techniques like contrastive learning and self-supervised pretraining. These advancements hold significant potential for improving clinical diagnostics (e.g., seizure detection, depression diagnosis), enhancing BCIs, and furthering our understanding of brain function.
