Unlike other methods that either assume or explicitly require defined absence locations, Presence-only Prediction can be applied to prediction problems where only the presence of the event is known. Potential applications While common examples relate to modeling species presence for ecological and ...
A PPS models a population of particles moving deterministically and asynchronously in a continuous toroidal wrapped space. Each particle is defined by its position pt = (xt, yt), by its heading ϕt, and by its movement with constant velocity v, assuming an open system allowing steady en...
