Abstract
A computer-implemented method of training an image analysis model. A coupling layer determines an output vector of integer values from an input vector of integer values. The coupling layer is applied by dividing the input vector into non-overlapping first and second input parts; applying a machine learnable submodel of the coupling layer to the first input part to obtain a submodel output of the machine learnable submodel; sampling a transformation vector from a discrete probability distribution, wherein the discrete probability distribution is parameterized based on the submodel output; determining a second output part based on the second input part and the transformation vector; and combining the first input part and the second output part to obtain the output vector. During backpropagation, a gradient of the sampling of the transformation vector is estimated.
