Highly Accurate Two-Dimensional Direction Finding Using Cumulant
IEEE Access, 2018 This paper proposes a new two-dimensional direction finding algorithm for estimating multiple non-Gaussian signals using cumulants. This new algorithm: 1) employs an array geometry consisting of a nine-element non-uniformly spaced cross-shaped sub-array ...

Single trial
Psychophysiology, 2012 AbstractThe extraction of task‐related single trial ERP features has recently gained much interest, in particular in simultaneous EEG‐fMRI applications. In this study, a specific decomposition known as parallel factor analysis (PARAFAC) was used, in order to retrieve the task‐related activity from the raw signals.

Parallel Factorization to Implement Group Analysis in Brain Networks Estimation
Sensors, 2023 When dealing with complex functional brain networks, group analysis still represents an open issue. In this paper, we investigated the potential of an innovative approach based on PARAllel FActorization (PARAFAC) for the extraction of the grand average connectivity matrices from both simulated and real datasets.
