針對其他目標最佳化解決方案

若要建立針對其他目標最佳化的解決方案，請使用下列create_solution方法。將 solution name、 dataset group arn和 recipe arn值取代為您自己的值。

對於 optimizationObjective，將 取代COLUMN_NAME為與您目標相關的項目資料集中的數值中繼資料資料欄名稱。針對 objectiveSensitivity，指定 OFF、MEDIUM、 LOW或 HIGH。

import boto3

personalize = boto3.client('personalize')

create_solution_response = personalize.create_solution(
    name= 'solution name', 
    recipeArn = 'recipe arn', 
    datasetGroupArn = 'dataset group arn',
    solutionConfig = {
        "optimizationObjective": {
            "itemAttribute": "COLUMN_NAME",
            "objectiveSensitivity": "MEDIUM"
        }
    }
)
solution_arn = create_solution_response['solutionArn']
print('solution_arn: ', solution_arn)

若要建立針對其他目標最佳化的解決方案，請使用下列createPersonalizeSolution方法，並將下列做為參數傳遞：Amazon Personalize 服務用戶端、資料集群組的 Amazon Resource Name (ARN)、解決方案名稱、配方 ARN、項目屬性和目標敏感度層級。

public static String createPersonalizeSolution(PersonalizeClient personalizeClient, 
                                             String datasetGroupArn, 
                                             String solutionName, 
                                             String recipeArn,
                                             String itemAttribute, 
                                             String objectiveSensitivity) {
    
    try {
        OptimizationObjective optimizationObjective = OptimizationObjective.builder()
            .itemAttribute(itemAttribute)
            .objectiveSensitivity(objectiveSensitivity)
            .build();
    
        SolutionConfig solutionConfig = SolutionConfig.builder()
            .optimizationObjective(optimizationObjective)
            .build();

        CreateSolutionRequest solutionRequest = CreateSolutionRequest.builder()
            .name(solutionName)
            .datasetGroupArn(datasetGroupArn)
            .recipeArn(recipeArn)
            .solutionConfig(solutionConfig)
            .build();

        CreateSolutionResponse solutionResponse = personalizeClient.createSolution(solutionRequest);
        
        return solutionResponse.solutionArn();

    } catch (PersonalizeException e) {
        System.err.println(e.awsErrorDetails().errorMessage());
        System.exit(1);
    }
    return "";
