Cool to see convolutions making such a comeback lately in the llm world. See also the recent striped hyena2 architecture, which uses the conv-based hyena operator to great success:
The null hypothesis is more compute or bigger network = better results. Conv operations make sense on images because the data is naturally 2 dimensional, so applying an operation across a sliding window makes sense.
Skimming the paper, I don’t see them testing against e.g. a normal decoder with an extra layer or something.
I don’t see the same logic applying on an embedding, where the individual indexes matter. Adjacent indexes in an embedding have no relationship, unlike adjacent pixels in an image.
