I couldn't find anything mentioned in amazon personalize SIMS and personalized ranking documentation regarding these recipes supporting user/item metadata. Does SIMS and personalized ranking support metadata?

"The Item-to-item similarities (SIMS) recipe is based on the concept of collaborative filtering. A SIMS model leverages user-item interaction data to recommend items similar to a given item. In the absence of sufficient user behavior data for an item, this recipe recommends popular items." [1]

Therefore, SIMS does not use metadata.

Personalized Ranking uses the Feature Transformer with ARN arn:aws:personalize:::feature-transformation/JSON-percentile-filtering This is the same as the ARN used by HRNN, which explicitly only uses interactions (there is an HRNN-Metadata recipe for that). [2][3][4]

Therefore, Personalized Ranking does not use metadata.

  • The info on Personalized-Ranking is no longer accurate. This recipe now trains on interactions (required) as well as item and user metadata if provided. https://docs.aws.amazon.com/personalize/latest/dg/personalized-ranking-recipes.html#personalized-ranking-overview – James J Nov 02 '22 at 23:09
