What deeplearning networks does pretrained models belongs to?

Hi i am working in Deeplearning (Classification) for my project and i am using some pretrained network like vgg16 , vgg19 ,Alexnet for my project and i want to know on what deepLearning framework basis that these pretrained networks are working .
Thanks in advance

Not sure about vgg (I haven't used them), but alexnet is a "convolutional neural network" used for classification (basically finding if the image has one of a predefined set of objects anywhere in the image - like "is there a dog, cat, or lizard anywhere in this image?").

I think you're in the wrong forum. A survey by Gartner showed MATLAB tools to be better than those but if you still want those tools, look in a forum that deals with those tools.

yes,sir,may be load the pretrained model,and check its Layers,use image reshape to match inputLayer size,then get the classify result through model Layers parameter compute. if want to watch middle layers work,may be use activations or deepDreamImage to view them, such as
net = alexnet;
net.Layers
