WebFrom the Keras documentation, description of the class_weight argument: Dictionary mapping class indices (integers) to a weight (float) value, used for weighting the loss function (during training only). This can be useful to tell the model to "pay more attention" to samples from an under-represented class. Web12 de dez. de 2024 · Typical Keras Model setup passing the loss function through model.compile () and target outputs through model.fit (). With DeepKoopman, we know the target values for losses (1) and (2), but y1 and y1_pred do not have ground truth values, so we cannot use the same approach to calculate loss (3).
