Abstract: Systems and techniques for enhancing the physical games with augmented reality is described. A system identifies a characteristic of a physical object that is located on a physical surface. The system obtains, based on the characteristic, information indicative of a rule set for the game and a state of the game based on the characteristic. A game engine is initialized based on the rule set and game state. The game engine generates a subsequent state for the game. The system renders, based on the subsequent state, an augmented reality display that incorporates the physical surface and physical object.

Abstract: A system obtains preference information by observing interaction, on behalf of a user, with a first service. A machine learning model is trained, based on the preference information. The system stores configuration data for the machine learning model. When a second service is invoked, the system provides the configuration data based at least in part on determining that the first and second services share a common classification. The second service reconstitutes the machine learning model and adjusts the interaction based at least in part on predictions made using the reconstituted machine learning model.
