Pruning and Compression as a Consequence of Sparse Attention
A direct consequence of the sparse attention assumption is the ability to prune the majority of attention weights. By disregarding the connections with near-zero weights, the attention model can be represented in a more compressed form, leading to significant computational savings.

KV Cache Requirement as a Limitation of Sparse Attention
Global Tokens in Attention
Comparison of Dense and Sparse Attention Matrices
A causal transformer model processes a sequence of 1024 tokens. In a standard attention mechanism, each token attends to all previous tokens and itself. Consider a 'sparse' variant where a token at position
i(fori > 3) only attends to the following positions: the first token (position 1), its own token (positioni), and the two immediately preceding tokens (positionsi-1andi-2). For a token at position 500, how many key-value pairs does it attend to in this sparse model?Computational Bottlenecks in Long-Sequence Processing

An engineer observes that in a particular attention mechanism, for any given piece of input text, each word focuses its attention heavily on only a very small number of other words. The attention scores for all other word-pairs are effectively zero. What is the most direct and significant advantage of this characteristic for the model's practical deployment?
Analyzing the Impact of Aggressive Model Pruning
A team of engineers is working on optimizing a large language model. They start with the observation that for any given token, most of the other tokens in the sequence have a negligible influence on its final representation. Arrange the following steps in the logical order that the team would follow to leverage this observation for computational efficiency.
