1. An electronic device, comprising:
a sensor that captures an image of a face and neck; and
body composition analysis circuitry that:
encodes a portion of the image into a latent space, wherein the latent space includes a first latent space representing a user identity, a second latent space representing a facial expression, and a third latent space representing a neck pose; and
determines a fat percentage value based on the portion of the image, wherein the body composition analysis circuitry compensates for the facial expression and the neck pose by removing the second and third latent spaces and using the first latent space to determine the fat percentage value based on the portion of the image.
