Adaptive Weighting Audio Matching Index

The patent applies local quality by allocating different numbers of descriptors to different reference samples based on their popularity. Popular reference samples (e.g., frequently matched audio content) are allocated more descriptors and interest points, while less popular samples receive fewer descriptors. This creates a non-uniform distribution of resources where each reference sample receives the appropriate level of detail based on local needs, thereby maintaining high matching accuracy for popular content while reducing overall storage requirements.

The patent implements partial action by generating multiple descriptors for each reference sample, but not all descriptors are used with equal weight. Instead, the system selectively applies descriptors based on their relevance and the specific matching context. The weighting mechanism applies partial action by emphasizing certain descriptors over others, allowing the system to achieve robustness to distortion without processing all possible descriptors equally, thus reducing computational complexity while maintaining reliability.

The patent applies dynamics by implementing an adaptive weighting system where the number of descriptors allocated to each reference sample is not fixed but dynamically adjusted based on popularity metrics. The system automatically updates descriptor allocations as popularity changes over time, allowing popular content to receive more descriptors when needed while maintaining simplicity in the underlying data structure. This dynamic approach resolves the contradiction by making the system adapt to changing requirements without requiring complex manual configuration.
