Context Before

A notable omission from Rubin is the mention of Sparse FLOPs. In previous generations, 2:4 structured sparsity was used to double marketing FLOPs numbers.

Evidence

However, adoption was minimal especially at low precisions due to accuracy losses from the rigid sparsity structure forcing half of the values to be zero.

Context After

Programmers basically ignored structured sparsity as it was not useful, which caused hardware designs to change as well.

② Atomic Claim

然而，structured sparsity 的採用率很低，尤其在 low precision 下，因為僵化的 sparsity 結構迫使一半數值歸零，造成 accuracy loss。

}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	sparsity	Sparsity

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
