Hot Coupling: a particle approach to inference and normalization on pairwise undirected graphs
by Firas Hamze, Nando Freitas — Advances in Neural Information Processing Systems
…This paper presents a new sampling algorithm for approximating functions of variables representable as undirected graphical models of arbitrary connectivity with pairwise potentials, as well as for estimating the notoriously difficult partition function of the graph. The algorithm fits into the fram…

Fast computational methods for visually guided robots
by Maryam Mahdaviani, O De Freitas, Bob Fraser, Firas Hamze — 2005 — The 2005 International Conference on Robotics and Automation (ICRA
…Abstract — This paper proposes numerical algorithms for reducing the computational cost of semi-supervised and active learning procedures for visually guided mobile robots from O(M 3) to O(M), while reducing the storage requirements from M 2 to M. This reduction in cost is essential for real-time in…
