The project “de retibus nummorum. Die Vernetzung der spätkeltischen Welt am Beispiel der Münzwirtschaft” (de re num), financed by the Deutsche Forschungsgemeinschaft has set up a blog on Hypotheses: https://derenum.hypotheses.org.
The project, which is based at Leipzig University, investigates the emergence and development of the Celtic monetary economy from the 3rd to 1st century BC. It incorporates type and die studies, supported by methods of artificial intelligence such as deep learning, as well as feature detection algorithms, into a social network analysis.
