Where do the algorithms come from?

The main one is FaceApiJS.

One I trained myself (BMI), and the others I just scavenged from existing Github projects. So with most of these I don't know how they were trained, what photos they were fed, etc.

How accurate is the BMI estimator? I trained one years ago, but the performance wasn't great.
