Webb24 dec. 2024 · Based on this observation, we propose a simplification of the non-local block, which explicitly learns global context other than pairwise relations. The resulting block, called the global context (GC) block, consumes significantly less computation than the non-local block but performs with the same accuracy on several important tasks. Webb22 jan. 2024 · Theoretically, a non-local block obtains the global context specific to each query position, but the global context after training is not affected by the query position. As shown in the structure in Fig. 2 c, GCNet simplifies the non-local block by sharing a query-independent (global) attention map for all query positions, based on Eq. 2. sharepoint online client id and client secret
