Personalization Model Transfer for Wireless Playback Devices

The patent introduces machine learning models as intermediary components that process wireless signal patterns to infer device locations. These models act as mediators between raw signal data and location information, transforming complex signal processing into accurate localization without requiring complex hardware modifications. The ML models serve as the intermediary layer that resolves the contradiction by providing high measurement precision through intelligent processing rather than hardware complexity.

The patent replaces traditional mechanical or hardware-based localization methods with software-based machine learning models. Instead of using complex hardware systems for localization, the invention substitutes them with AI models that process wireless signal patterns, thereby achieving high localization accuracy while maintaining relatively simple system hardware architecture.

The patent applies preliminary action by pre-training machine learning models during system setup or initialization phases. The models are trained on signal pattern data collected in advance to establish location mappings before actual use. This allows the system to achieve high location inference accuracy without requiring extensive real-time data collection, thereby reducing operational training time while maintaining precision.

The patent uses copying by creating trained ML models that capture the relationship between signal patterns and locations. Instead of collecting and processing all raw signal data in real-time, the system copies the learned patterns into pre-trained models that can quickly infer locations during operation. This copying approach maintains measurement precision while significantly reducing the time required for data processing during actual use.

The patent applies copying by creating portable playback devices that can copy personalization settings from source devices. The ML models trained on user preferences and signal patterns are copied to new devices, allowing seamless transfer of personalization without manual reconfiguration. This copying mechanism enhances adaptability while the automated nature of the process prevents significant increase in management complexity.

The patent implements self-service by enabling devices to automatically transfer their own personalization settings without requiring user intervention in the technical configuration process. The system self-manages the identification of matching devices through signal pattern recognition and automatically transfers relevant settings, thereby improving adaptability while keeping the complexity management burden on the system rather than the user.
