[digiKam-users] Face recognition got worse the more faces I have

[Kinh Nguyen]

As the title, the “main” faces in my photo collection have ~2000-3000 confirmed face. There are lots of faces of those same persons remain in Unknown, after several attempts to move the specificity slide up and down (70–90) using YOLO v3 detection. 

Some faces with fewer number of confirmed faces, though, have a better face suggestion. But also not able to give suggestion for the ones in Unknown.

Are there any way to e.g., choose another algorithm?
