Model description

Facial Confidence is an image classification model which takes a black and white image of a persons headshot and classifies it as confident or unconfident.

Intended uses & limitations

The model is intended to help with behavioral analysis tasks. The model is limited to black and white images where the image is a zoomed in headshot of a person (For best output the input image should be as zoomed in on the subjects face as possible without cutting any aspects of their head)
