[Dclib-devel] [dclib-devel] loss_mean_squared_per_pixel_ and gradient

[Eloi Du B. <elo...@gm...>]

I'm trying to make an 2d auto-encoder using loss_mean_squared_per_pixel.
It is really strange, I am getting a loss of 10e-5 on a training set, but
then, when I apply a forward pass on my validation set, which contains
something very very similar to the training set, I get an error of 0.1. I
think the problem is on my side, but I see something that I would like to
understand in this loss function:
In file loss.h +2421
It is written:
float* const g = grad.host();

On other functions I see:
float* const g = grad.host_write_only();

Could this be a problem? What is the difference?

Just want to make sure the GPU gradient is well updated.

Thanks,
