A question about the paper.

[xxxkkkmmm]

I am not a student of related majors, but I have a question need to understand. Excuse me, how does the 0.5 in the sentence "By default, a sequence with a score >0.5 would be regarded as a positive sample (a virulent phage) and a sequence with a score <0.5 would be regarded as a negative sample (a temperate phage)" in the article come from? Is it derived from the sigmoid function? I hope to get an answer, thank you very much!

It is set manually. You could change it by yourself according to the manual of DeePhage.
