How Meta Platforms Technologies Products Meta Horizon Worlds World Recommendations On Mixed Reality Horizon Feed works
The AI system behind Meta Horizon Worlds’ World Recommendations on MR Horizon Feed automatically gathers inventories that might be interesting to you, runs predictions to evaluate relevance, and delivers recommendations on your Feed. Here’s how it works:
  1. Gather Inventory
    First, the system gathers public Horizon Worlds eligible to be recommended. These might include Worlds that are currently popular and trending, Worlds your friends have visited, Worlds other users like you have enjoyed, or Worlds that are related to what you’ve recently engaged with.
  2. Make Predictions
    Second, the AI system runs predictions on how likely you will enjoy the content and assigns scores to the content based on the predictions.
  3. Apply Filters
    Next, the system applies integrity processes to remove content that is non-recommendable for quality reasons or that may go against our Code of Conduct for Virtual Experiences. We also remove worlds rated 18+ for certain age groups.
  4. Deliver Content
    Lastly, the scores are then used to decide what is recommended to you, where they appear in your Feed, and in which order you will see them.
