Particle in cell simulations are widely used in most fields of physics to investigate known and new phenomena which cannot be directly observed or measured yet. However, the computational and time resources needed for PICs make them impractical when

Empirically, it has been observed that adding momentum to Stochastic Gradient Descent (SGD) accelerates the convergence of the algorithm. However, the literature has been rather pessimistic, even in the case of convex functions, about the possibility

Este artigo ressalta alguns engajamentos da linguagem fotográfica de Éric Rondepierre, artista particularmente concernido pelas metamorfoses da imagem em razão da usura do tempo no dispositivo cinematográfico. Seu trabalho de arquivista e arqueó

Introduced by Beck and Teboulle, FISTA (for Fast Iterative Shrinkage-Thresholding Algorithm) is a first-order method widely used in convex optimization. Adapted from Nesterov's accelerated gradient method for convex functions, the generated sequence

We study the convergence of Nesterov Accelerated Gradient (NAG) minimization algorithm applied to a class of non convex functions called strongly quasar convex functions, which can exhibit highly non convex behaviour. We show that in the case of stro

When considering the minimization of a quadratic or strongly convex function, it is well known that first-order methods involving an inertial term weighted by a constant-in-time parameter are particularly efficient (see Polyak [32], Nesterov [28], an

La Photographie est par excellence le médium de la mise en évidence du dérisoire. Elle permet de cadrer spatialement le négligeable en vue de lui procurer une singularité. Seulement, la délimitation du cadrage n’est pas nécessairement spatia

We consider a combined restarting and adaptive backtracking strategy for the popular Fast Iterative Shrinking-Thresholding Algorithm frequently employed for accelerating the convergence speed of large-scale structured convex optimization problems. Se

A questão da temporalidade na construção da imagem fotográfica será aqui analisada. Para tal, o tempo é empregado como fundante na constituição da imagem, mas, do mesmo modo que a cria, é também o que a deteriora. Busca-se, com este estudo,
