Keras multiple output loss. Dec 15, 2020 · 3 my network has two outputs and single input. Jun 9, 2017 · In pseudo-code: loss = sum( [ loss_function( output_true, output_pred ) for ( output_true, output_pred ) in zip( outputs_data, outputs_model ) ] ) The functionality to do loss function on multiple outputs seems unavailable to me. Sep 19, 2022 · Introduction This example shows how to create a custom training step using the "Trainer pattern", which can then be shared across multiple Keras models. The common part of the network is shared between the two branches, and the gradients from the two branches are backpropagated separately to update the weights in the common part of the network. losses. .
