针对其他目标优化解决方案

要创建针对其他目标进行了优化的解决方案，请使用以下 create_solution 方法。将 solution name、dataset group arn 和 recipe arn 值替换为您自己的值。

对于 optimizationObjective，将 COLUMN_NAME 替换为物品数据集中与您的目标相关的数值元数据列名称。对于 objectiveSensitivity，请指定关闭、低、中或高。

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)

要创建针对其他目标进行了优化的解决方案，请使用以下 createPersonalizeSolution 方法并将以下内容作为参数传递：Amazon Personalize 服务客户端、数据集组的 Amazon 资源名称 (ARN)、解决方案名称、食谱 ARN、物品属性和目标敏感度级别。

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 "";

// Get service clients and commands using ES6 syntax.
import { CreateSolutionCommand, PersonalizeClient } from
  "@aws-sdk/client-personalize";

    }
  }
};

export const run = async () => {
  try {
    const response = await personalizeClient.send(new CreateSolutionCommand(createSolutionParam));
    console.log("Success", response);
