Is this related to lua's Torch at all? http://torch.ch/

They don't seem to explicitly say it, but it might be using the same core code given the structure of the framework and their mentioning that it's a mature codebase several years old. The license file also goes back to NYU before being taken over by Facebook, similar to Torch.

I am confused with the license file. What does it mean? Some rights reserved and copyright... Doesnt look like a real open source project.

Looks like standard BSD-3 to me

Copyrights are appropriate, they make it explicit who produced the work and make it easier to enforce the license. This license follows the general form of the BSD-style license [1].

It is a standard 3-clause BSD license. The "All rights reserved" portion definitely adds ambiguity (and only exists in the BSD license out of all major OSS licenses). There is StackExchange answer that goes into the history of it[1].

This project aside, I'm in love with that setup UI on the homepage telling you exactly how to get started given your current setup.

yes indeed!

I've never fiddled with machine learning thing so don't know anything about it.

I am wondering if CUDA is mandatory for torch installation ? I use a Macbook air which doesn't have graphics card, so not sure if torch can be installed and used on my machine.

At this point I've used PyTorch, Tensorflow and Theano. Which one do people prefer? I haven't done a ton of benchmarking, but I'm not seeing huge differences in speed (mostly executing on the GPU).

Got it. It makes sense now.

i've been running their dcgan.torch code in the past few days and results have been pretty amazing for plug and play

I believe that's a "no". I was able to set up a docker'ized Deep Style on my Macbook Pro, although it takes for bloody ever to do a single image. CUDA is, AFAIK, a substantial speed boost, but not a requirement.
