Data Collection Procedure #4

I am a bit confused by what you wrote in the paper at Section 2: Dataset

"The audio data collection duration is 10 minutes, where the feeding begins in the third minute, and the feeding process lasts about 3 minutes" . During the experiment, a total of 25 files of audio data, each of four minutes, from the beginning of feeding (the time for fish to swim to food is short, so it is ignored), were captured using a hydrophone according to the experience of farmers and technicians.

Then, "We further divide each one-minute audio clip into 30 seg- ments with each segment in two seconds. As a result, 3000 two-second audio clips are obtained, with 750 audio clips for each category of fish feeding intensity."

Can you clarify?

I'm sorry that our description has troubled you. The feeding process lasts about 3-15 minutes, but most data duration is about 10 minutes. Under the guidance of a fish-feeding technician, we annotated the feeding video data as “Strong”, “Medium”, “Weak” and “None”, based on the observed feeding intensity. To create a fine-grained dataset, we divided each one-minute video and audio clip into 30 segments with each segment in two seconds. We strongly recommend that you use our newly launched data set directly: https://github.com/FishMaster93/U-FFIA
