question in strong labels for evaluation #15

Open yongxuUSTC opened 6 years ago

yongxuUSTC commented 6 years ago

Why is there so many utterance without any label (totally empty)???

For example, the utterance starts from zero and ends also at zero, what does it mean? The problem is my trained model can always detect something, but the label is empty, leading to more insertion errors.

Hey there, I want to emphasize the problem by reporting all the utterances in question ( Overall 36 ). This reduces the amount of overall usable development utterances to 477 ( from 488 )

That is to say,delete the samples which the utterance starts from zero and ends also at zero?
