hi:
I have some questions on MELODIC:
1. Is PCA applied to the data before ICA is applied? (to decrease the dimentionality)
2. If PCA is applied as a preprocessing, where are those principal components fed into?(put it in this way: After PCA applied, we have a matrix E of some eigenvectors, is E same with X? where X=MS, X: mixed information, M: mixing matrix, S: source)
3: What criterion is used to extract those ICs by MELODIC? (minimize the negentropy?)
4. What on earth are those ICs, which are extracted by MELODIC?
Thanks a lot in advance
Xuelin
