Introducing the method of ellipcenters, a new first order technique for unconstrained optimization
Roger Behling, Ramyro Aquines Correa, Eduarda Ferreira Zanatta +1
In this paper, we introduce the Method of Ellipcenters (ME) for unconstrained minimization. At the cost of two gradients per iteration and a line search, we compute the next iterat…

Estimation of Spatiotemporal Poisson Processes with Some Missing Location Data
Vincent Guigues, Anton Kleywegt, Victor Hugo Nascimento +1
We consider models for spatiotemporal Poisson processes with some missing location data. We discuss four models that make provision for missing location data, and their estimation.…
