Keras smooth loss
Web20 jan. 2024 · In this article, we'll look at how you can use Label Smoothing in TensorFlow to help make your Tensorflow and Keras models more robust and prevent overfitting on your training data. TensorFlow makes it very easy to use Label Smoothing in existing codebases which we can easily add to the codebase by just adding a parameter.
