Where can I find a pre-trained variational autoencoder that's trained on natural images?

Does anyone know a pre-trained variational autoencoder (VAE) or a VAE-GAN that's trained on natural images? I have been searching for a variational autoencoder that is trained on natural images (e.g. ImageNet) where I can extract latent features…

Does keras have a pretrained AlexNet like VGG19?

If I want to use pretrained VGG19 network, I can simply do from keras.applications.vgg19 import VGG19 VGG19(weights='imagenet') Is there a similar implementation for AlexNet in keras or any other library?

ValueError: `decode_predictions` expects a batch of predictions (i.e. a 2D array of shape (samples, 1000)). Found array with shape: (1, 7)

I am using VGG16 with keras for transfer learning (I have 7 classes in my new model) and as such I want to use the build-in decode_predictions method to output the predictions of my model. However, using the following code: preds =…

Why do I have to do two train steps for fine-tuning InceptionV3 in Keras?

I don't understand why I have to call the fit()/fit_generator() function twice in order to fine-tune InceptionV3 (or any other pretrained model) in Keras (version 2.0.0). The documentation suggests the following: Fine-tune InceptionV3 on a new set…
