// DescribeRecipeRequest returns a request value for making API operation for
// Amazon Personalize.
//
// 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 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 GetRecommendations (https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html)
// API.
//
//    // Example sending a request using DescribeRecipeRequest.
//    req := client.DescribeRecipeRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
