Provides R functions which facilitate the estimation of ICA mixture models. We have developed and implemented the NSMM-ICA algorithm that currently integrates npEM and Fast-ICA for non-parametric estimation of ICA mixture models (Zhu, X., & Hunter, D.R., 2016 and Zhu, X., & Hunter, D.R., 2015 ). This is a new tool for unsupervised clustering.
