-- Describes a recipe.
--
-- A recipe contains three items:
--
-- -   An algorithm that trains a model.
--
-- -   Hyperparameters that govern the training.
--
-- -   Feature transformation information for modifying the input data
--     before training.
--
-- Amazon Personalize provides a set of predefined recipes. You specify a
-- recipe when you create a solution with the
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_CreateSolution.html CreateSolution>
-- API. @CreateSolution@ trains a model by using the algorithm in the
-- specified recipe and a training dataset. The solution, when deployed as
-- a campaign, can provide recommendations using the
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html GetRecommendations>
-- API.
