New York: Ieee, p. 581-588, 2014.http://hdl.handle.net/11449/184816In this paper, we presented a Graphics Processing Unit (GPU)-based training algorithm for Optimum-Path Forest (OPF) classifier. The proposed approach employs the idea of a vector-matrix multiplication to speed up both traditional OPF training algorithm and a recently proposed Central Processing Unit (CPU)-based OPF training algorithm. Experiments in several public datasets have showed the efficiency of the proposed approach, which demonstrated to be up to 14 times faster for some datasets. To the best of our knowledge, this is the first GPU-based implementation for OPF training algorithm.581-588engOptimum-Path ForestGraphics Processing UnitTrabalho apresentado em eventoWOS:000412737200071Acesso aberto
