Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data compression techniques fail to preserve cross-modal relationships between synchronized data streams, leading to artifacts during reconstruction, and lack adaptability to changing data characteristics, resulting in degraded performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional independent compression is applied to each data stream, then compression efficiency for individual modalities is optimized, but cross-modal relationships are lost or degraded
Solution Approach 1:
The patent merges multiple independent compression processes into a unified joint compression system that processes correlated data streams together. The joint codebook structure combines codebooks from different modalities (e.g., image, audio, sensor data) into a single compressed representation that preserves relationships between them, resolving the contradiction by maintaining cross-modal correlations while achieving compression efficiency.
Solution Approach 2:
The patent introduces correlation maps as intermediary structures that capture relationships between different data modalities. These correlation maps serve as mediators that guide the joint compression process, enabling the system to preserve cross-modal relationships during compression by using the correlation information to coordinate the compression of related data streams.
2Ease of manufacture
If static training datasets are used for codebook compression, then initial compression performance is achieved, but adaptability to changing data characteristics is lost
Solution Approach 1:
The patent transforms the static codebook structure into a dynamic one through continuous monitoring and adaptation mechanisms. The system monitors data distribution characteristics in real-time and automatically updates codebooks when distribution shifts are detected, enabling the compression system to adapt to changing data characteristics while maintaining good initial performance through the trained codebook structure.
Solution Approach 2:
The patent implements feedback loops where compression performance and data distribution characteristics are continuously monitored. When performance degradation or distribution shifts are detected, the system triggers codebook updates or retraining processes, creating a closed-loop system that maintains adaptability to changing data while preserving the benefits of initial training.
3Manufacturing precision
If compression is applied to preserve cross-modal relationships, then reconstruction quality is improved, but computational complexity increases
Solution Approach 1:
The patent segments the joint compression process into manageable components: individual modality encoding, correlation map generation, and joint codebook construction. This segmentation allows the system to preserve cross-modal relationships through structured processing while reducing computational complexity by breaking down the overall task into efficient sub-tasks that can be processed separately and then integrated.

AI summary
A correlation-aware adaptive codebook compaction system for multi-modal data compression that preserves cross-modal relationships while providing enhanced reconstruction quality. The system analyzes temporal and spatial relationships between different data modalities to generate correlation maps that guide compression decisions. A virtual management layer performs stream characterization and adaptive routing, while a processing pipeline implements primary codebook compression with mismatch handling for novel data blocks. High-entropy data segments receive pre-compression processing before codebook compression. Sequential registration data is processed through matrix factorization and dedicated matrix codebooks. The system continuously monitors data distribution characteristics and automatically retrains codebooks when drift thresholds are exceeded. A neural upsampling subsystem uses correlation information to guide cross-modal enhancement processes through modality-specific networks and attention mechanisms. The unified output includes compressed data streams, correlation maps, synchronization metadata, neural model parameters, and updated codebooks, enabling synchronized reconstruction with preserved cross-modal relationships and enhanced quality through correlation-guided neural upsampling.
