How do you classify an EEG signal?

The types of EEG waves[2,3] are identified according to their frequency range – delta: below 3.5 Hz (0.1–3.5 Hz), theta: 4–7.5 Hz, alpha: 8–13 Hz, beta: 14–40 Hz, and gamma: above 40 Hz.

What is motor imagery classification?

Motor imagery classification is an important topic in brain-computer interface (BCI) research that enables the recognition of a subject's intension to, e.g., implement prosthesis control.

What is motor imagery EEG?

A motor imagery-based brain-computer interface (MI-BCI) creates a path through which the brain interacts with the external environment by recording and processing electroencephalograph (EEG) signals made by imagining the movement of a particular limb. From: Artificial Intelligence-Based Brain-Computer Interface, 2022.

What are features in EEG data?

The simplest features of the EEG signal are statistical features, like mean, median, variance, standard deviation, skewness, kurtosis, and similar [50].
