WebDec 15, 2024 · You can wrap Tensorflow's tf.losses.huber_loss in a custom Keras loss function and then pass it to your model. The reason for the wrapper is that Keras will only pass y_true, y_pred to the loss function, and you likely want to also use some of the many parameters to tf.losses.huber_loss. So, you'll need some kind of closure like: WebSmooth L1 loss is closely related to HuberLoss, being equivalent to h u b e r (x, y) / b e t a huber(x, y) / beta h u b er (x, y) / b e t a (note that Smooth L1’s beta hyper-parameter is also known as delta for Huber).
