Claim 6:
7. A method for generating clinically similar synthetic cases to an existing case using a probabilistic encoder-decoder having a latent space, the method comprising:
inputting data x0, x1, . . . xn for a plurality of cases and a condition c into the probabilistic encoder to produce a corresponding plurality of samples z0, z1, . . . zn in a latent space;
generating m random samples around the sample z0; and
inputting the m samples around the sample z0 into the probabilistic encoder to produce m synthetic cases,
wherein the probabilistic encoder-decoder having a latent space, is trained to produce the latent space by minimizing the reconstruction loss and using a regularization effect to force clinically similar inputs to be close together in the latent space by minimizing a Kullback-Leibler divergence between the clinically similar inputs.
