Transfer Learning - include_top

The Keras website has a lot of good information, including documentation of all the pretrained models they have, example code to do fine-tuning and tutorials about Transfer Learning. Here’s the top level Keras page for that, which starts with the catalog of all the models they have.

Here’s the next level down that is specific to the MobilNet models. That page in turn points to some other great resources:

Examples of image processing Transfer Learning use cases.

Transfer Learning and Fine-Tuning. That page looks like the one that will really address your questions about freezing and unfreezing layers. Please have a look! It’s basically an online version of a chapter from François Chollet’s (the author of Keras) book about Keras. I haven’t read it in detail yet, but just scanned through and it looks like it covers things thoroughly with lots of example code.
