Abstract
A method performed by at least one processing device in an illustrative embodiment comprises applying an input data sample to an encoder of an encoder-decoder network to generate a corresponding latent representation, combining the latent representation from the encoder with noise, applying the combined latent representation and noise to a decoder of the encoder-decoder network to generate an estimated data sample, and outputting the estimated data sample. Respective sets of parameters of the encoder and decoder of the encoder-decoder network are configured based at least in part on an iterative optimization process utilizing a task loss determined from a task function that relates the input data sample to a task output. A given iteration of the iterative optimization process illustratively generates an estimated task output from the estimated data sample, determines a loss measure using the estimated task output, and adjusts one or more parameters using the loss measure.
