Learning a Fourier Transform for Linear Relative Positional Encodings in Transformers

AISTATS 2024poster

We propose a new class of linear Transformers called FourierLearner-Transformers (FLTs), which incorporate a wide range of relative positional encoding mechanisms (RPEs). These include regular RPE techniques applied for sequential data, as well as novel RPEs operating on geometric data embedded in h…

From block-Toeplitz matrices to differential equations on graphs: towards a general theory for scalable masked Transformers

ICML 2022spotlight

In this paper we provide, to the best of our knowledge, the first comprehensive approach for incorporating various masking mechanisms into Transformers architectures in a scalable way. We show that recent results on linear causal attention (Choromanski et al., 2021) and log-linear RPE-attention (Luo…
