Abstract
The invention relates to a technique for pre-training a principal encoder and a concept head. A method comprises receiving, at a principal encoder (302), a medical image (502) and processing it for obtaining a principal latent representation (504), which is provided to a concept head (306) and to a style head (310) to obtain a first vector of discretized anatomical concepts and an associated further first vector of continuous styles per discretized anatomical concept in the medical image (502), respectively. An auxiliary feature decoder determines, based on the obtained first vector of discretized anatomical concepts, an auxiliary latent representation (10), based on which an auxiliary image decoder (316) performs a reconstruction (512) of the medical image (502). The principal encoder (302) and concept head (306) are pre-trained based a reconstruction loss between the received medical image (502) and the first reconstruction (512).
