Ole Christian Eidheim

About

Lecturing, or have been lecturing, in the fields of programming, information management, mathematics, machine learning, software development, information security, networking, and 3D visualisation.

My research field is within machine learning, particularly more biologically plausible artificial intelligence, but I have also been developing open, and general software and software libraries, most notably: juCi++, Simple-Web-Server, Simple-WebSocket-Server, tiny-process-library, Skeletal-Animation-Library, and react-simplified.
