Despite its simplicity, random search remains one of the important base-lines against which to compare the performance of new hyperparameter optimization methods. Methods such as Bayesian optimization smartly explore the space of potential choices of hyperparameters by deciding which combination to explore next based on previous observations.
Guided Local Search — modification of search algorithms which builds up penalties during a search; Reactive search optimization (RSO) — the algorithm adapts its parameters automatically; MM algorithm — majorize-minimization, a wide framework of methods; Least absolute deviations. Expectation–maximization algorithm
The algorithm described herein is a type of local random search, where every iteration is dependent on the prior iteration's candidate solution. There are alternative random search methods that sample from the entirety of the search space (for example pure random search or uniform global random search), but these are not described in this article.
The result of combining this grid with the previous grid is a grid which gives the probability of finding the wreck in each grid square of the sea if it were to be searched. At the end of October 1968, the Navy's oceanographic research ship, Mizar , located sections of the hull of Scorpion on the seabed, about 740 km (400 nmi; 460 mi) southwest ...
Pattern search (also known as direct search, derivative-free search, or black-box search) is a family of numerical optimization methods that does not require a gradient. As a result, it can be used on functions that are not continuous or differentiable. One such pattern search method is "convergence" (see below), which is based on the theory of ...
Tabu search (TS) is a metaheuristic search method employing local search methods used for mathematical optimization. It was created by Fred W. Glover in 1986 [ 1 ] and formalized in 1989. [ 2 ] [ 3 ]
It was argued that PICO may be useful for every scientific endeavor even beyond clinical settings. [2] This proposal is based on a more abstract view of the PICO mnemonic, equating them with four components that is inherent to every single research, namely (1) research object; (2) application of a theory or method; (3) alternative theories or methods (or the null hypothesis); and (4) the ...
Compared with Wolfe's conditions, which is more complicated, Armijo's condition has a better theoretical guarantee. Indeed, so far backtracking line search and its modifications are the most theoretically guaranteed methods among all numerical optimization algorithms concerning convergence to critical points and avoidance of saddle points, see ...
