Capsule Network for ERP Detection in Brain-Computer Interface

چکیده

Event-related potential (ERP) is bioelectrical activity that occurs in the brain response to specific events or stimuli, reflecting electrophysiological changes during cognitive processes. ERP important neuroscience and has been applied brain-computer interfaces (BCIs). However, because signals collected on scalp are weak, mixed with spontaneous electroencephalogram (EEG) signals, their temporal spatial features complex, accurate detection challenging. Compared traditional neural networks, capsule network (CapsNet) replaces scalar-output neurons vector-output capsules, allowing various input information be well preserved capsules. In this study, we expect utilize CapsNet extract discriminative spatial-temporal of encode them capsules reduce loss valuable information, thereby improving performance for BCI. Therefore, propose ERP-CapsNet perform a BCI speller application. The experimental results Competition datasets Akimpech dataset show achieves better classification performances than do state-of-the-art techniques. We also use decoder investigate attributes ERPs encoded relies P300 P100 components detect ERP. not only acts as an outstanding method detection, but provides useful insights into mechanism.

Computer-Aided Tinnitus Detection based on Brain Network Analysis of EEG Functional Connectivity

Background: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation and disruption of the brain net...

Optimum Spatio-Spectral Filtering Network for Brain-Computer Interface

This paper proposes a feature extraction method for motor imagery brain-computer interface (BCI) using electroencephalogram. We consider the primary neurophysiologic phenomenon of motor imagery, termed event-related desynchronization, and formulate the learning task for feature extraction as maximizing the mutual information between the spatio-spectral filtering parameters and the class labels....
