This paper introduces a crowd modeling and motion control approach that employs diffusion adaptation within an adaptive network. In the network, nodes collaboratively address specific estimation problems while simultaneously moving as agents governed by certain motion control mechanisms. Our researc…
Brain interictal epileptiform discharges (IEDs) are transient events occurring between two or before seizure onsets. The IEDs are captured mainly by the intracranial EEG (iEEG) and only 4.7% of them are visible in our scalp EEG (sEEG) dataset. Here, we propose a method namely temporal components ana…
Interictal epileptiform discharges (IEDs) can have various morphologies as well as spatial distributions and sometimes are associated with other brain activities, resulting in uncertainty in their labeling. Such an uncertainty corresponds to the probability of a waveform being an IED. Here, we incor…
Bursts of sleep spindles and paroxysmal fast brain activity waveforms have frequency overlap whilst generally, paroxysmal waveforms have shorter duration than spindles. Both resemble bursts of normal alpha activity during short rests while awake with closed eyes. In this paper, it is shown that for…
In this article, detection of sleep apnea or hypopnea events is addressed using a single channel electrocardiography (ECG) signal by analysis of respiratory extracted modulation. First, R peaks are detected from ECG signal. Then, a time-series with the amplitude (height) and timing of R peaks repres…
Quaternion adaptive line enhancer (QALE) has been proposed recently for the recovery of two- (2-D) or three-dimensional (3-D) periodic signals from their noisy mixtures [1] with the help of quaternion-valued adaptive filtering theory. Similar to the traditionall-D [2] version, QALE, relies mainly on…
This paper focuses on learning a coupled dictionary between multimodal datasets where the data of different modes can be described as a function of each other. Our method is able to reconstruct the data of one mode by using the data of another mode. This provides the advantage on applications that l…
The recent introduction of η-Hermitian matrices A = A <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ηH</sup> has opened a new avenue of research in quaternion signal processing. However, the exploitation of this matrix structure has been limited, perh…
