Claim 18:
19. A system for improving an operation of a variational autoencoder, comprising: a hardware processor; a memory device coupled with the hardware processor; the hardware processor configured to at least: train a generator network of a variational autoencoder to approximate a simulator and generate a first result, wherein the simulator having been run prior to training the generator network, given input data, outputs output data that simulates output of an entity the simulator is simulating, the first result generated by the generator network being an approximation of the simulator's output data, wherein a training data set for the generator network includes the simulator's input data and output data, wherein the generator network receives the simulator's input data as generator network's input and the generator network learns to approximate the simulator's output data based on being trained on the training data set, wherein the variational autoencoder's latent space matches an input space of the simulator; based on the simulator's output data and the first result of the generator network, train an inference network of the variational autoencoder to generate a second result, the second result approximating the simulator's input data, the second result of the trained inference network inverting the first result of the generator network, the trained inference network functioning as an inverted simulator, wherein the training of the generator network and the inference network of the variational autoencoder is decoupled.
