We demonstrate this approach on images of spatial deposition from a pollution source, where the encoder compresses the dimensionality to 0. 02% of the original size, and the full predictive model performance on test data achieves a normalized root mean squared error of 8%, a figure of merit in space of 94% and a precision-recall area under the curve of 0. 93.
