imdb structure of caltech101

I want to pass arguments to @ccn_train function in matconvent for retraining alexnet on caltech 101 dataset. It requires imdb structure of caltech101. Can anyone please guide me how to create the imdb.mat (having data, labels,set,sets).

[Anas Samara]

Please help in this?

You'd probably be better off asking the developers of the matconvnet toolbox. This is not native Matlab.

Have you read the documentation on their site?

[neena aloysius]

Yes, I have gone through their documentation but no much details about setting up of imdb

[Guillaume]

They have a discussion forum. You would be better asking there.

You're not going to find many people here that know about matconvnet AND imdb structure (whatever that means). From the lack of responses, I would guess that number of people is 0.

edit: Well, 1 as it turns out.

I know a small bit about both of those, but I am overloaded and do not have the resources to take this on.

There are difficulties compiling matconvnet on OS-X and difficulties compiling on Windows

I have some virtual machines running MS Windows, in which I have installed various MATLAB versions, but one thing I have not done is install any compilers -- I would have to clone off a new 140 GB virtual machine each time because the compiler installations interact with each other so in order to be able to accurately log what needs to be done for each setup, I would need the equivalent of a clean install. It also turns out that CUDA is not available to virtual machines except possibly by using a university project whose site has not been reachable when I tried. I dislike booting up into MS Windows directly, it's like driving backwards on the wrong side of the road -- possible but Not Fun.

Hi. Download the caltech101 dataset. This folder has .mat file with dataset variables. You can edit/use those variables in cnn training. Good luck!
