This paper shows empirically and theoretically that randomly chosen trials are more efficient for hyper-parameter optimization than trials on a grid. Empirical evidence comes from a comparison with a large previous study that used …

The complex mechanism of the method makes theoretical analysis difficult. Therefore, simplified versions of RF, called purely RFs (PRF), which can be theoretically handled more easily, have been considered.

Such optimization methods are also known as direct-search, derivative-free, or black-box methods. Anderson … See more Let f: ℝ → ℝ be the fitness or cost function which must be minimized. Let x ∈ ℝ designate a position or candidate solution in the search-space. The basic RS algorithm can then be described as: 1.
