Decision Tree Data Content Selection for Real-Time User Preference Matching

The patent transitions from static periodic offline model updates to dynamic real-time model updates. The match model is continuously updated as user behavior data arrives, ensuring the model always reflects the latest user preferences and behavior patterns. This dynamic approach resolves the contradiction by maintaining high accuracy through continuous updates without requiring complex batch processing infrastructure.

The system implements self-updating capability where the match model automatically incorporates new user behavior data without requiring manual intervention or complex offline processing. The model serves itself by continuously learning from incoming data streams, thereby maintaining high selection accuracy while avoiding the complexity of manual model retraining and deployment cycles.

The patent segments the model update process into incremental updates based on individual user browsing events rather than requiring full model retraining. Each user interaction triggers a localized update to relevant model components, which reduces overall system complexity while maintaining real-time accuracy. This segmentation allows the system to handle real-time updates efficiently without overwhelming computational resources.

The system performs partial updates only on the portions of the match model affected by new user behavior data, rather than updating the entire model. This partial action approach maintains high accuracy for relevant user segments while significantly reducing computational complexity and resource requirements compared to full model retraining.
