Photos recognition algorithm is not recognizing faces that it used to recognize.
Seems that the Photos facial recognition algorithm is not recognizing faces that it used to recognize. Over the last 15 years I have built a Photos library of over 20,000 pictures and 150 faces. The software used to be very good at recognizing new instances of faces it identified before and NEVER forgot the original face. Now it seems to forget faces randomly and switches them, e.g. identifying a picture of my wife as aa picture of someone I work with or as a stranger of the bus! How do I fix this???
