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: WebOct 10, 2014 · What you're aksing is basically for a smoothed method for $ {L}_{1} $ Norm. The most common smoothing approximation is done using the Huber Loss Function. Its gradient is known ans replacing the $ {L}_{1} $ with it will result in a smooth objective function which you can apply Gradient Descent on.

WebNov 17, 2024 · Huber Loss is often used in regression problems. Compared with MSE, Huber Loss is less sensitive to outliers as if the loss is too much it changes quadratic equation to linear and hence is a combination of both MSE and MAE. Image by Author Advantages a) Outliers are handled properly. b) Local minima situation is handled here. … WebThis is often referred to as Charbonnier loss [5], pseudo-Huber loss (as it resembles Huber loss [18]), or L1-L2 loss [39] (as it behaves like L2 loss near the origin and like L1 loss elsewhere). Our loss’s ability to express L2 and smoothed L1 losses is sharedby the “generalizedCharbonnier”loss[34], which

WebJun 5, 2024 · Huber loss can be really helpful in such cases, as it curves around the minima which decreases the gradient. And it’s more robust to outliers than MSE. Therefore, it combines good properties from both MSE and MAE. However, the problem with Huber loss is that we might need to train hyperparameter delta which is an iterative process. 4. Log ...
