A reward request is a feedback on how well the personalized content or action is performed for the user. It contains a numerical value that represents the reward or outcome of the personalization. You can send requests and rewards using REST APIs or SDKs in various languages, such as C#, Python, Java, etc.
• Monitor and evaluate: You can monitor and evaluate how it is performing and learning using the Azure portal or the CLI. You can see metrics such as average reward, rank distribution, feature importance, etc. You can also download logs and reports for further analysis.
