Difference of calling the Keras pretrained model without including top layers
What is the difference of calling the VGG16 model with or without including top layers of the model? I wonder, why the input parameters to the layers are not shown in the model summary when the mo...

How to reuse VGG19 for image classification in Keras?
I am currently trying to understand how to reuse VGG19 (or other architectures) in order to improve my small image classification model. I am classifying images (in this case paintings) into 3 clas...

Training accuracy is ~97% but validation accuracy is stuck at ~40%
I am trying to classify images into 27 classes using a Conv2D network. The training accuracy rises through epochs as expected but the val_accuracy and val_loss values fluctuate severely and are not...

How do I find which rpm package supplies a file I'm looking for?
As an example, I am looking for a mod_files.sh file which presumably would come with the php-devel package. I guessed that yum would install the mod_files.sh file with the php-devel x86_64 5.1.6-23.2.
