\

\ Subsequently, the aggregated low-rank matrix can be reintegrated with the original embeddings, as shown in Equation 9. This low-rank projection effectively reduces the time complexity to O(MM′).

\

\ Proposition 2. MIVPG, when equipped with the CSA (Correlated Self-Attention) module, continues to fulfill the essential properties of MIL

\ We prove the proposition 2 in the supplementary B.

\ In summary, as depicted in Figure 2a, we establish that QFormer falls under the MIL category and is a specialized instance of our proposed MIVPG. The latter extends to visual inputs with multiple dimensions, accounting for instance correlation.
