I see that q2-feature-classifier classify-sklearn has a default 0.7 confidence score. Where does this value come from? I found this reply by @Nicholas_Bokulich saying that this value was adjusted based on benchmarking results, but there is no reference associated. Was this published or was it an unpublished analysis by the QIIME 2 team? Are there any confidence scores benchmarking papers out there?
Thank you very much,
