Hi,
I have two different image data-set but related to a same class. I am going to use pre-trained net like alexnet for both to detect features and then, concatenate those features into a classifier (and optimize this classifier not the whole models). I would appreciate if you can help me within this context. Here is the pseudo code:

Alexnet(Image I) --> Feature I
Alexnet(Image II) --> Feature II
Concatenate (Feature I, Feature II) --> Feature
Feature --> Classifier
Optimize Step 4

Thanks in advance,
