@ryota.matsuda I believe you are looking for active learning feature which is available with some of the LLM offerings of Azure Cognitive services. In this case with FR, this is not a feature with FR custom models where the models self-learn from the images provided to the analyze API. The quality of the results needs to be monitored for confidence scores and new models need to be trained and then included as part of composed model with old and new models to get better results. So, this is part of developmental effort to manage custom models and improve them as required. I hope this helps!!
