WebThis is how we can freeze certain layers of pre-loaded models. We can access model layers we want to freeze, either by using the get layer method as we do here, or by indexing into model.layers and set the trainable attribute to be false. The layer will then … WebHow can I "freeze" Keras layers? To "freeze" a layer means to exclude it from training, i.e. its weights will never be updated. This is useful in the context of fine-tuning a model, or using fixed embeddings for a text input. You can pass a trainable argument (boolean) to a layer constructor to set a layer to be non-trainable: frozen_layer ...

In this blog we will present a guide for transfer learning with an example implementation in Keras using ResNet50 as the trained model. The case is to transfer the learning of a ResNet50 trained with Imagenet to a model that identify images from CIFAR-10 dataset. The final model of this blog we get an accuracy of 94% on test set.

The from and to layer arguments are both inclusive. When applied to a model, the freeze or unfreeze is a global operation over all layers in the model (i.e. layers not within the specified range will be set to the opposite value, e.g. unfrozen for a call to freeze).
