Research on Reconstruction Factor Model of Old Residential Area Based on Multi-Modal Data Fusion

The green transformation of old residential areas is a major livelihood project and development project to promote urban renewal and meet the needs of the people for a better life, and an important way to realize the sustainable development of stock buildings.Firstly, in the transformation elements, an adaptive modal weight updating mechanism is designed to dynamically adjust the modal weights in the process of coclustering fusion, so as to meet the dynamic change requirements of the modal influence on the fusion results and improve the scalability of the algorithm.Secondly, the evaluation index system of comprehensive elements of green transformation in old residential areas is established and improved, and the attribute hierarchy model is used to determine the index weights.Finally, taking the reconstruction elements of old residential areas as the basic unit of matters-element extension theory, the multi-modal data fusion reconstruction element model is constructed, which provides a new perspective and new ideas for the formulation of old residential areas reconstruction plan.
