title: .mat files as input for caffe deep learning network
body: <p>Is it possible to use .mat files to store input data for the caffe deep learning framework? if yes, how can I change the 'data' of my train_val.prototxt? I am using the googlenet network.</p>
  
  <p>If no, which other file formats can I use rather than mdb and hd5?</p>
  
  <p>For me, using .mat files is better because of their size, my .hd5 files are huge (caffe can't read them because of lack of memory) and I can't find how to save my data as .mdb files in Matlab.</p>
