In conducting mood analysis while eating by use of EEG, counted on an objective method of preference survey. Artifacts induced by masticatory muscular activities (principally in the masseter muscle) contaminate EEG observations, and it is necessary to remove such artifacts from EEG. In our previous report, Independent Component Analysis (ICA) was introduced to blindly remove the artifacts from EEG, especially based on an instantaneous mixture model. In this report, we examine their propagation delay of several miliseconds through the scalp, when they pass on the face instantly, which seems to be the reason why ICA for the instantaneous mixture model yields to unsatisfactory results. In addition, frontal pole above the orbit has a peculiar propagation style. We tried to remove the artifacts by FDICA of the convolutive mixture model, and have succeeded in two observed signals. For the multiple signals (more than three), FDICA has still not shown good performance. This might be because of the permutation problem and the approximation error of the demixing matrix. An application of a robust blind deconvolution algorithm to more than three multiple signals is to be studied. |
