Implementation of the model "Hedgehog" from the paper: "The Hedgehog & the Porcupine: Expressive Linear Attentions with Softmax Mimicry". This paper implements MLPs to mimic the softmax of a transformer. Suppodesly hits SOTA on wikitext for sub quadratic models. I've too been thinking about replacing softmax with MLPs. This past month we saw doezens of papers on mamba and convolutions but MLPs might have undiscovered powers.
