Parallel Processing

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Automatic Processing and Automatic Social Behavior

Automatic Processing and Automatic Social Behavior

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Background:

Early brain-computer interface (BCI) systems relied on neurophysiological knowledge and feedback training.
Current state-of-the-art BCIs utilize data-driven, machine learning (ML) methods, yet performance limitations hinder widespread adoption.

Purpose of the Study:

To propose a novel, automatic feature selection method for BCIs.
To enhance BCI performance by integrating data-driven approaches with expert knowledge using a fuzzy logic (FL) system.

Main Methods:

Developed an automatic feature selection method leveraging both data-dependent and expert knowledge.
Employed a fuzzy logic (FL) system to suppress noisy features and highlight relevant ones.
Fused heterogeneous information channels to increase decision-making reliability while maintaining transparency.

Main Results:

Demonstrated significant improvements in classification accuracy.
Showcased enhanced feature stability and reduced class bias.
Validated the method on large motor imagery datasets, including end-users with motor disabilities.

Conclusions:

Combining data-driven methods with neuroscience knowledge via FL can improve BCI performance.
The proposed FL-based approach enhances BCI explainability and learnability.
This method offers a promising direction for advancing BCI technology for practical applications.
