The best-performing model in terms of both classification accuracy and the most common calibration measure, expected calibration error (ECE) was the Confidence Weight method, a novel approach that weights the loss of samples to explicitly penalise confident incorrect predictions.

Our key contribution is that the VAE disentangles the latent space based on `explanations' drawn from existing clinical knowledge.
