Hi,
I have recently used NMF in sklearn for unmixing/end member detection and it was much faster compared to the implementation we have in pysptools.
We can use end member matrix U user provides and …

Hey there,
I just debugged the `ICA.plot_components()` method and stumbled over the docstring in [topomap.py#L778](https://github.com/mne-tools/mne-python/blob/master/mne/viz/topomap.py#L778), wher…

Dear @mbillingr and @cbrnr ,
I am very interest in the example script 'statistics.py', here I have one question about it:
``` do_mvarica(varfit='class')```
1. I saw the introduction:```varfit='cl…

I'd like to run ICA only on specific time segments within my (BrainVision) raw data. I have these segments given in two `np.arrays`, one with the start samples and one with the stop samples, e.g.

CB says: in my opinion, they are not really related to spectral unmixing:
- spectralDist (and cos.dist?) may be best in ChemoSpec?
- I could also imagine hosting cos.dist in hyperSpec (which already h…

I recently got into a small trouble:
Description: When I set _n_ for the value of n_components in and ICA decomposition and _n_ < Picks, it results in an ica object with a mixing_matrix_.shape of _n_…
