Echo: Error-Compensated 4-Bit Tensor-Parallel Communication for LLM Training and Inference

Xingyu Xie, Xiaoyong Xie, Zhouchen Lin +1

Tensor parallelism ends every layer with an all-reduce that sits between two dependent matrix multiplications, so its cost cannot be hidden and grows as compute outpaces interconne…

Establishing Boundary KKT Convergence of Mirror Descent through Reparameterization

Kuangyu Ding, Kim-Chuan Toh

Sequence convergence to a boundary Karush--Kuhn--Tucker (KKT) point has long remained unclear for nonconvex mirror descent with Legendre kernels. The difficulty arises from the blo…

Non-KKT Accumulation in Entropic Mirror Descent

Kuangyu Ding, Kim-Chuan Toh

For mirror descent generated by a Legendre kernel, perhaps one of the most basic question in optimization is this: must every accumulation point of a bounded mirror descent sequenc…

Slow-Fast Inference: Training-Free Inference Acceleration via Within-Sentence Support Stability

Xingyu Xie, Zhaochen Yu, Yue Liao +3

Long-context autoregressive decoding remains expensive because each decoding step must repeatedly process a growing history. We observe a consistent pattern during decoding: within…

Towards Understanding Why FixMatch Generalizes Better Than Supervised Learning

Jingyang Li, Jiachun Pan, Vincent Y. F. Tan +2

Semi-supervised learning (SSL), exemplified by FixMatch (Sohn et al., 2020), has shown significant generalization advantages over supervised learning (SL), particularly in the cont…

Optimization Hyper-parameter Laws for Large Language Models

Xingyu Xie, Kuangyu Ding, Shuicheng Yan +2

Large Language Models have driven significant AI advancements, yet their training is resource-intensive and highly sensitive to hyper-parameter selection. While scaling laws provid…
