I am currently undertaking my PhD in a very niche sub field of Artificial Intelligence. However, I have, what I consider, a strong background in programming and often contribute to many open source projects in my spare time. I have recently started an Open Source project which solves a very particular problem, but is outside the scope of my PhD research.
I wish to publish my hobby research and I doubt this is something my project supervisors, or university would be interested in. Should I go ahead and publish without their knowledge, or should I ethically bring it to their attention before I send it off? It should be noted, because it is my hobby project, I don't particularly want it influenced by an academic agenda.
