About this paper

Andrew Mouldon

MoC makes short causal convolution token-dependent by mixing learned local filters according to each token, while retaining the same short window. The authors apply it separately to projected queries, keys, and values. Across evaluated Transformer and Gated DeltaNet settings, MoC lowers FineWeb-Edu and WikiText-103 perplexity than static convolution; at 460M parameters, FineWeb-Edu perplexity is 13.67 versus 13.82, within tests up to 15B training tokens.
