You have an app named App1 that uses the Face API.
App1 contains several PersonGroup objects.
You discover that a PersonGroup object for an individual named Ben Smith cannot accept additional entries. The PersonGroup object for Ben Smith contains
10,000 entries.
You need to ensure that additional entries can be added to the PersonGroup object for Ben Smith. The solution must ensure that Ben Smith can be identified by all the entries.
Solution: You modify the custom time interval for the training phase of App1.
Does this meet the goal?

A. Yes
B. No

Show Suggested Answer

Suggested Answer: B 🗳️
Instead, use a LargePersonGroup. LargePersonGroup and LargeFaceList are collectively referred to as large-scale operations. LargePersonGroup can contain up to 1 million persons, each with a maximum of 248 faces. LargeFaceList can contain up to 1 million faces. The large-scale operations are similar to the conventional PersonGroup and FaceList but have some differences because of the new architecture.

B. No Modifying the custom time interval for the training phase of App1 will not resolve the issue of the PersonGroup object for Ben Smith reaching its capacity and being unable to accept additional entries. Changing the training interval will only affect the training process of the Face API, which is unrelated to the capacity of a PersonGroup object. To enable additional entries for Ben Smith, you would need to either increase the capacity of the PersonGroup object or create a new PersonGroup object for Ben Smith with a higher entry limit.

Looks like this can be a possible solution too. Besides LargePersonGroup which is also correct. I'm choosing Yes for Custom Interval and for LargePersonGroup. https://docs.microsoft.com/en-us/azure/cognitive-services/face/face-api-how-to-topics/how-to-use-large-scale#step-31-customize-time-interval

Rethinking because the Customize Time Interval applies only if entries are migrated to LargePersonGroup.
