Description
Hi,
I have been exploring your implementation and came across the parameters topk_ratio and local_range. Could you please clarify the following points?
topk_ratio:
What does the topk_ratio parameter control in your model? How does it relate to the resolution of the input data?
local_range:
What is the role of local_range in the attention process? How does it constrain the attention span or locality?
Additionally, I am interested in understanding the Locality-Constrained Sparse Attention mechanism. Specifically:
Where is the implementation of Locality-Constrained Sparse Attention in the codebase?

Research direction
Search the codebase for the topk_ratio and local_range parameters and trace their use in the Locality-Constrained Sparse Attention implementation. Read the surrounding attention code to determine how each parameter affects resolution, attention span, and locality. Done means documenting these roles and identifying the implementation location for users.
