Transformers Can Implement Preconditioned Richardson Iteration for In-Context Gaussian Kernel Regression
Mingsong Yan, Dongyang Li, Charles Kulick +1
In this paper, we study in-context kernel ridge regression (KRR) with Gaussian kernels and show, both theoretically and empirically, that a standard softmax-attention transformer c…

Random space-time sampling and reconstruction of sparse bandlimited graph diffusion field
Longxiu Huang, Dongyang Li, Sui Tang +1
In this work, we investigate the sampling and reconstruction of spectrally -sparse bandlimited graph signals governed by heat diffusion processes. We propose a random space-time…
