ERROR in compute NMF method 'brunet'

Donatella93 commented 9 months ago

Hi! I keep getting this error while computing NMF with different methods. This ERROR occur for methods 'brunet', 'KL' and others, but NOT for 'lee' and 'Frobenius' methods that work OK

I have a matrix with 130 rows (samples/obs) x 79 columns (features)

meth <- nmfAlgorithm(all = TRUE) estim.r <- nmf(data, 2:6, method = meth, nrun=200, seed=123456)

Compute NMF method 'brunet' [2/16] ... Timing stopped at: 1.83 0.01 17.47 Timing stopped at: 1.92 0.02 17.27 Timing stopped at: 1.89 0.03 16.29 Timing stopped at: 1.83 0 16.64 Timing stopped at: 1.87 0.03 15.86 ERROR

Did anyone already deal with this issue?

Thanks

I have the same problem. Did you solve it?

Hi! I edited my dataset (containing binary data only), by removing columns and rows where the sum of values was 0 and I did not get anymore that error. I can suggest you to check your data, and maybe it will help!

Good luck!
