Online metrics are the empirical results observed in your user’s interactions with real-time recommendations provided in a live environment.Īmazon Personalize generates offline metrics using test datasets derived from the historical data you provide. ![]() ![]() Offline metrics allow you to view the effects of modifying hyperparameters and algorithms used to train your models, calculated against historical data. You can measure the performance of ML recommender systems through offline and online metrics. ![]() The following diagram represents which tasks Amazon Personalize manages. Record new user-item interactions in real time by streaming events to an event tracker attached to your Amazon Personalize deployment.Deploy an Amazon Personalize-managed, real-time recommendations endpoint (also known as a campaign).Based on your use case, start a training job using an Amazon Personalize ML algorithm (also known as recipes).Import your historical user-item interaction data.You can quickly create a real-time recommender system on the AWS Management Console or the Amazon Personalize API by following these simple steps: A frequently asked question is, “How do I compare the performance of recommendations generated by Amazon Personalize to my existing recommendation system?” In this post, we discuss how to perform A/B tests with Amazon Personalize, a common technique for comparing the efficacy of different recommendation strategies. ![]() With Amazon Personalize, you can solve the most common use cases: providing users with personalized item recommendations, surfacing similar items, and personalized re-ranking of items.Īmazon Personalize automatically trains ML models from your user-item interactions and provides an API to retrieve personalized recommendations for any user. Customers in industries such as retail, media and entertainment, gaming, travel and hospitality, and others use Amazon Personalize to provide personalized content recommendations to their users. Amazon Personalize allows you to easily add sophisticated personalization capabilities to your applications by using the same ML technology used on for over 20 years. Machine learning (ML)-based recommender systems aren’t a new concept, but developing such a system can be a resource-intensive task-from data management during training and inference, to managing scalable real-time ML-based API endpoints.
