Fusing Cross-Domain Knowledge from Multimodal Data to Solve Problems in the Physical World
This paper proposes a four-layer framework (Domains, Links, Models, Data layers) to define and solve cross-domain multimodal data fusion problems, particularly for real-world physical problems. It addresses challenges like data selection, knowledge alignment, and representation learning by providing systematic methodologies, including principles for knowledge alignment (multiview-based, similarity-based, dependency-based, commonality-based), two knowledge fusion paradigms (precise and coarse), and data transformation approaches (preprocessing, precise, coarse). The framework aims to reduce data collection effort, improve forecast accuracy, enable earlier anomaly detection, and provide more reliable estimations by leveraging existing data across diverse domains.

Urban Air Quality Forecasting Case Study
A real-world example demonstrating the application of Multiview-based knowledge alignment for improved air quality prediction.
Case Study: Urban Air Quality Forecasting
Challenge: Predicting fine-grained air quality across a city is complex due to diverse contributing factors (traffic, land use, meteorology) and insufficient local sensor data.
Solution: Leveraging multimodal data from different domains (e.g., traffic conditions, POIs, meteorological data) and applying the Multiview-based knowledge alignment principle. Three predictors (temporal, spatial, inflection) act as different views.
Results: Achieved more accurate forecasts and better understanding of complex environmental phenomena than single-source models. Reduced data collection burden.
Data Transformation Importance
Transforming data of different structures, resolutions, scales, and distributions is essential for effective AI model input.
