TDM (International Patent)

TDM – Temporal Diffusion Model (International Patent)

Which entity at the time (n) influences which other entities at the time (n+1), and with which strength; in a different way, which is the causation process? The Target Diffusion Model (TDM) will try to answer to this point.

An example from Assisi 1995-2008 displacements:
