This work presents a novel approach for discriminating complex mental and motor tasks using diffusion adaptation and brain connectivity measures. In particular, in this paper, we use a S-transform based measure to estimate the connectivity on single-trial basis and diffusion Kalman filtering to train a model that can classify different tasks. The superiority of the method is proven when compared with...
In this paper we model the biological networks of bacteria and antibacterial agents and investigate the effects of cooperation in the corresponding self-organized networks. The cooperative foraging of the bacteria has been used to solve non-gradient optimization problems. In order to obtain a more realistic model of the process, we extend the previously introduced strategies for bacteria motility...
Diffusion adaptation combined with an adaptive way of estimating brain connectivity is used here in order to model specific motor tasks. We use Kalman filtering to fit an adaptive multivariate autoregressive model to our data and compute the connectivity measure which is a time-varying version of directed transfer function (DTF). The resulting method is used to classify the data from movement-related...
This work examines the flow of information among electrodes attached to the brain and uses diffusion adaptation strategies to assess brain cortical connectivity. The method uses the directed transfer function (DTF) technique to estimate combination coefficients to drive the adaptation and learning process. The diffusion strategy is then applied to the problem of recognizing left and right hand movements...
