KV Cache Requirement as a Limitation of Sparse Attention

Global Tokens in Attention

Pruning and Compression as a Consequence of Sparse 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 (for i > 3) only attends to the following positions: the first token (position 1), its own token (position i), and the two immediately preceding tokens (positions i-1 and i-2). For a token at position 500, how many key-value pairs does it attend to in this sparse model?

Linear Causal Attention Formula

Normalization Transformation in Linear Attention

A language model is being optimized to process very long sequences of text while minimizing memory consumption during inference. The standard attention mechanism is replaced with an alternative approach that applies a kernel function to the query and key vectors and omits the Softmax operation. This change allows the order of matrix multiplications to be rearranged. Which of the following best analyzes the primary benefit of this modification?

Optimizing a Long-Context Language Model

A language model is being modified to use a memory-efficient attention mechanism for processing long documents. This involves altering the standard attention calculation. Arrange the following steps in the logical order they occur in this modified process.

Attention Mechanism Efficiency Analysis

In an effort to optimize an attention-based model, a researcher modifies the standard multi-head attention mechanism. The new design shares a single Key (K) and Value (V) projection across all attention heads, while each head continues to use its own unique Query (Q) projection. Which statement best analyzes the primary trade-off of this architectural change?
