In single-hop needle-in-a-haystack tasks, critical KV pairs are naturally prominent in attention scores, making it nearly impossible for compression methods to drop them, making these tasks too 'friendly' to compression methods.

UnverifiedMany long-context evaluation tasks can be solved under Sliding Window Attention (SWA), so strong performance on these tasks cannot prove that compression methods are effective in scenarios that genuinely require long-range dependencies.75% similarUnverifiedMany sparse/compression evaluation tasks can be passed under sliding window attention, so the 5–10x compression ratios reported on these tasks are not convincing.75% similarUnverifiedSingle-hop needle-in-a-haystack tests, contaminated benchmarks, and few-shot in-context learning tasks are the three categories most favorable to compression and sparse methods, with most being passable under sliding window attention.72% similarUnverifiedIn scenarios with frequent overlapping and occlusion among multiple people, the bottom-up approach is more robust but has higher computational complexity.71% similarUnverifiedThe root cause of attention dilution lies in Softmax normalization: the more tokens in a sequence, the effective attention weight allocated to each position decreases approximately inversely proportional to the sequence length.69% similar
