AI Technical Summary

Technical Problem

Existing technologies face challenges in processing multi-source heterogeneous data, including significant differences in cross-domain distribution, fragmented data structures, and inconsistent modal characteristics. This leads to difficulties in cross-domain alignment, poor fusion results, weak generalization ability of prediction models, and a lack of flexibility in adapting to different scenarios.

Method used

A smart city environmental health and safety risk prediction system based on multimodal perception is adopted. Through heterogeneous data acquisition, domain alignment, joint representation learning and AI large model risk prediction module, cross-domain distribution alignment and modal-level feature calibration are achieved by using a bi-adversarial domain alignment neural network and a weak parameter sharing mechanism. Heterogeneous feature weighted fusion is carried out by combining a time-series-space-graph structure three-stream feature fusion network.

Benefits of technology

It significantly improves cross-domain alignment, enhances the model's generalization ability and prediction accuracy, has strong adaptability, supports flexible switching in different scenarios, reduces deployment costs, and enhances the model's robustness and anti-interference ability.
