  "Description": "Provides an implementation of the Sparse ICA method in\nWang et al. (2024) <doi:10.1080/01621459.2024.2370593> for\nestimating sparse independent source components of cortical\nsurface functional MRI data, by addressing a non-smooth,\nnon-convex optimization problem through the relax-and-split\nframework. This method effectively balances statistical\nindependence and sparsity while maintaining computational\nefficiency.",
