Toolkit crash during clustering with "--problem with a KL -2.22045e-16"

[glynpu]

Hi Srikanth,

I am re-implementing your paper 'Two-Pass IB based Speaker Diarization System using Meeting-Specific ANN based Features'. Parameters like beta, NMI threshold, maximum segment duration are set according to the paper. Scp files are converted from AMI labels. 19 MFCCs are extract by HTK as input features.

For some audio files in AMI-1 data-set, this toolkit works pretty well. However, in case of ES2013c, the toolkit crash with the following prompt. Could you give a clue about what mistakes I have made?

Another problem is about the feature used in this paper. Could you recommend a toolkit to extract MFS (Mel Filterbank Slope) and Linear Filterbank Slope (LFS) features?

Thanks for your time and patience.
Best wishes,

Liyong Guo

Hello,

Thank you for your feedback. I need to replicate your
problem with the file mentioned. Could you please give more
details about:

1. Feature configuration used to generate HTK features
2. Segmentation used

For MFS/LFS, we have not yet made the feature extractors
open source, but it is possible to implement it using simple
linear regression on log filterbank energies.

Thanks,
Srikanth

Hi Srikanth,

Thank you for your kind help.

I upload the config and scp files here

To replicate my problem, just run diartk.sh in the above repository.
