Web8 Apr 2024 · TensorFlow/Theano tensor. y_pred: Predictions. TensorFlow/Theano tensor of the same shape as y_true. So if we want to use a common loss function such as MSE or Categorical Cross-entropy, we can easily do so by passing the appropriate name. A list of available losses and metrics are available in Keras’ documentation. Custom Loss Functions WebThis makes it usable as a loss function in a setting where you try to maximize the proximity between predictions and targets. If either y_true or y_pred is a zero vector, cosine similarity will be 0 regardless of the proximity between predictions and targets. loss = -sum (l2_norm (y_true) * l2_norm (y_pred)) Standalone usage:
