Analysis of a Sparse Attention Strategy
A research team is developing a language model for processing extremely long documents. To manage computational costs, they implement an attention strategy where, for any given token, it only attends to (1) the first 50 tokens of the document and (2) the 25 tokens immediately preceding and succeeding it. This pattern is applied consistently to all documents, regardless of their content. Analyze the fundamental principle that defines this attention mechanism and explain why this approach is more computationally efficient than a standard attention mechanism.

Extended Sparse Attention
An engineer designs a sparse attention mechanism where, for any given token at position
i, the model is only allowed to attend to the tokens within a fixed-size window around it (e.g., from positioni-ktoi+k). This rule is applied uniformly across the entire sequence, irrespective of the specific words involved. Which statement best analyzes the core principle of this design?Analysis of a Sparse Attention Strategy
In a positional-based sparse attention mechanism, the set of tokens that a given token attends to is dynamically adjusted during processing based on the semantic similarity of the surrounding tokens.
