Training our own networks

Hello everyone! Super excited to be able to use this cutting edge tech.

I have looked all over on how to train my own network, and saw a mention in this article

“At this time, in order to use DLSS to its full potential, developers need to provide data to NVIDIA to continue to train the DLSS model. The process is fairly straightforward with NVIDIA handling the heavy lifting via its Saturn V supercomputing cluster.”

Are we actually able to send data to Nvidia to aid them in training the network? Can we train our own networks locally? Thank you for any input you might have!
