This loss is equal to the negative log probability of the true class: It is zero if the model is sure of the correct class. This untrained model gives probabilities close to random (1/10 for each class), so the initial loss should be close to -tf.math.log(1/10) ~= 2.3 loss_fn(...
The TensorFlow platform assists in implementing the best applications for data automation, model tracking, performance monitoring, and model retraining. Production-level instruments are used to automate and trace the training of the model over the lifespan of a product, service, or business process i...
1. Note: It is possible to bake this tf.nn.softmax in as the activation function for the last layer of the network. While this can make the model output more directly interpretable, this approach is discouraged as it's impossible to provide an exact and numerically stable loss calculation ...
