چکیده
Abstract Objective. In the last decade, advent of code-modulated brain-computer interfaces (BCIs) has allowed implementation systems with high information transfer rates (ITRs) and increased possible practicality such interfaces. this paper, we evaluate effect different numbers targets in stimulus display, modulation sequences generators, signal processing algorithms on accuracy ITR BCIs. Approach. We use both real simulated electroencephalographic (EEG) data, to these parameters methods. Then, compared numerous setups assess their performance identify best configurations. also evaluated dependability our evaluation approach. Main results. Our results show that Golay, almost perfect, deBruijn sequence-based visual modulations provide results, significantly outperforming commonly used m-sequences all cases. conclude artificial neural network offer pipeline for type BCI, achieving a maximum classification 94.7% EEG data while obtaining 127.2 bits min ?1 64-target system. Significance. framework demonstrated previously unattainable flexibility convenience staying reasonably realistic. Furthermore, findings suggest several new considerations which can be guide further code-based BCI development.

How does a brain build a cognitive code?
This article indicates how competition between afferent data and learned feedback expectancies can stabilize a developing code by buffering committed populations of detectors against continual erosion by new environmental demands. The gating phenomena that result lead to dynamically maintained critical periods, and to attentional phenomena such as overshadowing in the adult. The functional unit...
متن کاملEEG Filtering Optimization for Code-Modulated Chromatic Visual Evoked Potential-Based Brain-Computer Interface
We present visual BCI classification accuracy improved results after application of high– and low–pass filters to an electroencephalogram (EEG) containing code–modulated visual evoked potentials (cVEPs). The cVEP responses are applied for the brain–computer interface (BCI) in four commands paradigm mode. The purpose of this project is to enhance BCI accuracy using only the single trial cVEP res...
متن کاملBuild Fast and Accurate Lemmatization for Arabic
In this paper we describe the complexity of building a lemmatizer for Arabic which has a rich and complex derivational morphology, and we discuss the need for a fast and accurate lammatization to enhance Arabic Information Retrieval (IR) results. We also introduce a new data set that can be used to test lemmatization accuracy, and an efficient lemmatization algorithm that outperforms state-of-t...
متن کاملA Fast and Accurate Isotachophoresis Simulation Code
We developed a numerical code which allows fast and accurate simulation of isotachophoresis (ITP). The multi-species code accounts for equilibrium chemistry, non-uniform electroosmotic flow, and dispersion. Our modeling efforts for the latter are also presented. The goal of our work is to create an efficient, accurate, validated, and uniquely-capable electrophoresis simulation code available fo...
متن کاملStudy of EEG signals to build a man-computer interface
Following recent developments in numerical elaboration and electro-physiological science many researchers now believe its possible to build a man-computer interface EEG based. We know that hand movements are accompanied by changes of some EEG features. These changes are called event-related desynchronisations (ERDs) and are picked-up especially in the mu-band (8-12 Hz). We also know ERDs are b...
