WebbWe analyze the coordinate descent method with a new coordinate selection strategy, called volume sampling. This strategy prescribes selecting subsets of variables of … Randomized (Block) Coordinate Descent Method is an optimization algorithm popularized by Nesterov (2010) and Richtárik and Takáč (2011). The first analysis of this method, when applied to the problem of minimizing a smooth convex function, was performed by Nesterov (2010). In Nesterov's analysis the … Visa mer The following Figure shows how $${\displaystyle x_{k}}$$ develops during iterations, in principle. The problem is Visa mer One can naturally extend this algorithm not only just to coordinates, but to blocks of coordinates. Assume that we have space $${\displaystyle R^{5}}$$. This space has 5 coordinate directions, concretely Visa mer • Coordinate descent • Gradient descent • Mathematical optimization Visa mer
