# **Age-Classification-SigLIP2**  

> **Age-Classification-SigLIP2** is an image classification vision-language encoder model fine-tuned from **google/siglip2-base-patch16-224** for a single-label classification task. It is designed to predict the age group of a person from an image using the **SiglipForImageClassification** architecture.

The model categorizes images into five age groups:  
- **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+"
