MetaCLIP-2-Age-Range-Estimator

MetaCLIP-2-Age-Range-Estimator is an image classification vision-language encoder model fine-tuned from facebook/metaclip-2-worldwide-s16 for a single-label classification task. It is designed to predict the age range of a person from an image using the MetaClip2ForImageClassification architecture.

The model categorizes images into five age ranges:

• Class 0: "Child 0-12"
• Class 1: "Teenager 13-20"
• Class 2: "Adult 21-44"
• Class 3: "Middle Age 45-64"
• Class 4: "Aged 65+"
