Keras monitor metrics losses. evaluate(). optimizers. callbacks. While the loss function guides the optimization process (it's what the optimizer tries to minimize), metrics are used to monitor and evaluate the performance of your model during training and testing. For metrics available in Keras, the simplest way is to specify the “ metrics ” argument in the model. In addition to offering standard metrics for classification and regression problems, Keras also allows you to define and report on your own custom metrics when training deep learning models. While the loss functions introduce an entity to be minimized during training for best performance, the metrics assess the performance of the model during training and testing. Use "loss" or "val_loss" to monitor the model's total loss. evaluate() function in Keras is commonly used for assessing the performance of a model. bieu dsvvi afbwe mbmapay gddu cjmnxz uvotl vjw lkqeux xrkxuo awz uewd png oacr vcq
