Low-Rank Tucker-2 Model for Multi-Subject fMRI Data Decomposition with Spatial Sparsity Constraint
Han, Yue; Lin, Qiu-Hua; Kuang, Li-Dan; Gong, Xiao-Feng; Cong, Fengyu; Wang, Yu-Ping; Calhoun, Vince D. (Institute of Electrical and Electronics Engineers (IEEE), 2022)Tucker decomposition can provide an intuitive summary to understand brain function by decomposing multi-subject fMRI data into a core tensor and multiple factor matrices, and was mostly used to extract functional connectivity ... -
Discovering hidden brain network responses to naturalistic stimuli via tensor component analysis of multi-subject fMRI data
Hu, Guoqiang; Li, Huanjie; Zhao, Wei; Hao, Yuxing; Bai, Zonglei; Nickerson, Lisa D.; Cong, Fengyu (Elsevier, 2022)The study of brain network interactions during naturalistic stimuli facilitates a deeper understanding of human brain function. To estimate large-scale brain networks evoked with naturalistic stimuli, a tensor component ... -
Model order effects on ICA of resting-state complex-valued fMRI data : application to schizophrenia
Kuang, Li-Dan; Lin, Qiu-Hua; Gong, Xiao-Feng; Cong, Fengyu; Sui, Jing; Calhoun, Vince D. (Elsevier BV, 2018)Background Component splitting at higher model orders is a widely accepted finding for independent component analysis (ICA) of functional magnetic resonance imaging (fMRI) data. However, our recent study found that intact ... -
Spatial source phase : A new feature for identifying spatial differences based on complex-valued resting-state fMRI data
Qiu, Yue; Lin, Qiu-Hua; Kuang, Li-Dan; Gong, Xiao-Feng; Cong, Fengyu; Wang, Yu-Ping; Calhoun, Vince D. (John Wiley & Sons, Inc., 2019)Spatial source phase, the phase information of spatial maps extracted from functional magnetic resonance imaging (fMRI) data by data‐driven methods such as independent component analysis (ICA), has rarely been studied. ... -
Spatio-temporal Dynamical Analysis of Brain Activity during Mental Fatigue Process
Zhang, Chi; Sun, Lina; Cong, Fengyi; Ristaniemi, Tapani (IEEE, 2021)Mental fatigue is a common phenomenon with implicit and multidimensional properties. It brings dynamic changes of functional brain networks. However, the challenging problem of false positives appears when the connectivity ...
