ask for some details about the model directory

[canneltigrou]

Hi, I would like to use your project in order to read a Torch model on an embedded system. But I don't understand the two files that are required into the model directory.

I would like to use Openface (https://cmusatyalab.github.io/openface/) : they use a lua script to open the model, but I have only one file : the model named nn4.small2.v1.t7

concerning your two files :

• model.net the network file saved in .t7 format. I suppose I have just to rename my file into "model.net"
• stat.t7 contains a table with a 'std' and 'mean' FloatTensor of dimension 3. I don't understand what is this file ?

thanks for any answer,

Hi,

stat.t7 is used to put the input image into the right range. It basically just subtracts mean from the input and divides it by std; mean and std are specified for each color plane. If you don't provide that file, mean will be 0 and std 1, leaving your input as is.

Best regards, Marko.
