Exact Causal Attention with 10% Fewer Operations

Dmitry Rybin, Yushun Zhang, Ding Tian +2

We present Exact Causal Attention (ECA), a Strassen-style algorithm that computes exact Causal Attention using 10\% fewer operations. ECA improves a special class of matrix multipl…

Finite Horizon Optimization: Framework and Applications

Yushun Zhang, Dmitry Rybin, Zhi-Quan Luo

In modern engineering scenarios, there is often a strict upper bound on the number of algorithm iterations that can be performed within a given time limit. This raises the question…

Zeroth-Order Optimization Meets Human Feedback: Provable Learning via Ranking Oracles

Zhiwei Tang, Dmitry Rybin, Tsung-Hui Chang

In this study, we delve into an emerging optimization challenge involving a black-box objective function that can only be gauged via a ranking oracle-a situation frequently encount…

FFLV polytopes for odd symplectic Lie algebras

Dmitry Rybin

We consider "odd symplectic Lie algebras" defined in terms of maximal rank skew-symmetric forms. We provide FFLV polytopes for these algebras and prove their standard properties. I…
