New linearized attention model achieves higher accuracy and lower perplexity

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a linearized version of 2-simplicial attention, which rewrites the trilinear score into an inner product. This new form allows for linear cost in sequence length while maintaining global reach, unlike traditional windowed attention mechanisms. By approximating the sum with positive random features and storing past information in a fixed-size state, this method can be implemented with custom Triton kernels and integrated with Kimi Delta Attention. The resulting model, which omits softmax attention entirely, has demonstrated superior downstream accuracy and improved perplexity on benchmarks like LAMBADA. AI

IMPACT This research introduces a more efficient attention mechanism that could lead to faster and more accurate language models.

    Linearized 2-Simplicial Attention

    arXiv:2608.09307v1 Announce Type: new Abstract: We present a linearized form of 2-simplicial attention by rewriting the trilinear score as an inner product between a composite query and a key, so that the sum over one token axis takes the same form as ordinary softmax attention. …
