  "Description": "A direct and flexible method for estimating an ICA model.\nThis approach estimates the densities for each component\ndirectly via a tilted Gaussian. The tilt functions are\nestimated via a GAM Poisson model. Details can be found in\n\"Elements of Statistical Learning (2nd Edition)\" in Section\n14.7.4.",
