WebNotice that you are not merging two models (in the sense of keras Model) in the above, you're merging layers. In Keras there is a helpful way to define a model: using the functional API. With functional API you can define a directed acyclic graphs of layers, which lets you build completely arbitrary architectures. WebFreeze the layers of the VGG16 model up to the last convolutional block Note that: in order to perform fine-tuning, all layers should start with properly trained weights: for instance you should not slap a randomly initialized fully-connected network on top of a pre-trained convolutional base.
