Kedar S. Prabhudesai, Boyla O. Mainsah, Leslie M. Collins, Chandra S. Throckmorton

ICASSP 2018accepted

Latent Dirichlet allocation (LDA) is a statistical model that is often used to discover topics or themes in a large collection of documents. In the LDA model, topics are modeled as discrete distributions over a finite vocabulary of words. The LDA is also a popular choice to model other datasets span…

A performance-based approach to designing the stimulus presentation paradigm for the P300-based BCI by exploiting coding theory

B. O. Mainsah, Leslie M. Collins, Galen Reeves, Chandra S. Throckmorton

ICASSP 2017accepted

The P300-based brain-computer interface (BCI) speller relies on eliciting and detecting specific brain responses to target stimulus events, termed event-related potentials (ERPs). In a visual speller, ERPs are elicited when the user's desired character, i.e. the “target,” is flashed on a computer sc…
