Does segments order in scp file matter? #15

Open glynpu opened 7 years ago

glynpu commented 7 years ago

Hi Srikanth,

With the default data and configuration in this package, I got an 8.79 diarization error, which is exactly the same with the expected one.

However, when I move the last ten segments to the beginning of the file ./data/AMI_20050204-1206.scp, the dearization error becomes 9.4(miss 4.3 and speaker error 5.1). Comparing with the default 8.79(miss 2.1 speaker error 6.7), there seems to be more parts are missed.

Is it normal? Is there a recipe to put the segments to get the best performance?

Best wishes, Liyong Guo

Hello,

I confirm the issue. If the scp file is not sorted, the 10 segments at the beginning are discarded. This seems to be the origin of the issue. This is the reason the miss percentage has increased. I will fix this and get back.

Thanks for the feedback, Srikanth
