Exam AI-102 topic 2 question 13 discussion

Box 1 is "findsimilars", others do not match the given request body and make no sense anyway. https://docs.microsoft.com/en-us/rest/api/faceapi/face/find-similar

findsimilars and matchPerson https://docs.microsoft.com/en-us/rest/api/faceapi/face/find-similar?tabs=HTTP#find-similar-results-example "matchPerson" is the default mode that it tries to find faces of the same person as possible by using internal same-person thresholds. It is useful to find a known person's other photos. Note that an empty list will be returned if no faces pass the internal thresholds. "matchFace" mode ignores same-person thresholds and returns ranked similar faces anyway, even the similarity is low. It can be used in the cases like searching celebrity-looking faces.

This is useful for doing a face search by image.

Box 1 - FindSimilar Box 2 - matchPerson (We have to find based on a sample photo)

Seems FIND SIMILAR AND MATCHPERSON

Looking at the ENTIRE document the answer has to be findsimilar: You cannot send the properties like faceListID and largeFaceListId to /detect

The Answer is correct. The question asks to "find photos of a person based on a sample image". Key is "based on a sample image". Only detect does this : https://docs.microsoft.com/en-us/rest/api/faceapi/face/detect-with-url. Find Similars is used to search the similar-looking faces from a faceId array, a face list or a large face list
