As a pivotal research method in the field of granular computing (GrC), fuzzy rough sets (FRSs) have garnered significant attention due to their successful overcoming limitations traditional handling continuous data. This paper is dedicated exploring application potential FRS models within framework multi-source complex information systems, which undoubtedly holds profound significance. Firstly, novel mixed system (MsMIS), encompassing five distinct data types, introduced, thereby enriching dimensions processing. Subsequently, similarity function, designed based on unique attributes data, utilized accurately quantify relations among objects. Building this foundation, T-norm operators are employed integrate matrices derived from different types into cohesive whole. integration not only lays solid foundation for subsequent model construction but also highlights value fusion analysis MsMIS. The integrated results subsequently develop models. Through rigorous examination perspective granularity, rationality proven, and its mathematical properties explored. contributes theoretical advancement GrC offers promising prospects practical implementation.

Multisource and multimodal data fusion plays a pivotal role in large-scale artificial intelligence applications involving big data. However, the choice of strategies for different scenarios is often based on experimental comparisons, which leads to increased computational costs during model training suboptimal performance testing. In this paper, we present theoretical analysis early fusion, late gradual methods. We derive equivalence conditions between fusions within framework generalized linear models. Moreover, analyze failure presence nonlinear feature-label relationships. Furthermore, propose an approximate equation evaluating accuracy methods as function sample size, feature quantity, modality number. also critical size threshold at dominance models undergoes reversal. Finally, introduce method selection paradigm selecting most appropriate prior task execution demonstrate its effectiveness through extensive numerical experiments. Our expected solve problems resource construction, improving scalability efficiency
