## Description

Random search (RS) is a

**family of numerical optimization methods**that do not require the gradient of the problem to be optimized, and RS can hence be used on functions that are not continuous or differentiable. Such optimization methods are also known as direct-search, derivative-free, or black-box methods.Sep 14, 2020 — Random search is appropriate for discovering new hyperparameter values or new combinations of hyperparameters, often resulting in better ...

Jun 14, 2018 — Random search is a technique where random combinations of the hyperparameters are used to find the best solution for the built model.

Mar 30, 2021 — Random search is a method in which random combinations of hyperparameters are selected and used to train a model.
