Incorrect index in LFR

[louisabraham]

I'm pretty sure it should be

dists = np.zeros((N, k))

as dists matches the distance between each data sample and prototype.

That sound right and thanks for pointing this out.

The final results should not be affected as M_nk loops over k.

[louisabraham]

Yes, as long as k < P (else you have a bound error).

[pronics2004]

Yes, you are right. Thanks. Should be fixed in PR #84.
