Audacity has added AI audio editing capabilities thanks to Intel’s free OpenVINO plugins. These plugins add AI-powered noise suppression, speech transcription, music generation and remixing, and music separation to the freeware sound editor and are available for download today.
There are graph neural networks (meaning NNs that work on graphs), but I don’t think that’s what is used here.
I do not understand what you mean by “routes”. I suspect that you have misunderstood something fundamental.
You can see a neural net as a graph in that the neurons are connected nodes. I don’t believe that graph theory is very helpful, though. The weights are parameters in a system of linear equations; the numbers in a matrix/tensor. That’s not how the term is used in graph theory, AFAIK.
ETA: What you say about “routes” (=paths?) is something that I can only make sense of, if I assume that you misunderstood something. Else, I simply don’t know what that is talking about.
If you look at the nodes which are most likely to trigger from given inputs then you can draw paths
I still don’t know what this is supposed to mean for neural nets. I think it reflects a misunderstanding.
