Alignment Drift in Single-Model Speculative Decoding for ASR: Mechanism, Correction, and Cost

Xinyu Wang, Huapeng Zhou, Ziyu Zhao +5

Speculative decoding speeds up generation by letting a cheap draft propose several tokens that a target model checks in one pass. In the single-model form, the draft is a lightweig…

The $I ¨ _{y}$ -genus, Chern number inequalities and signature

Ping Li, Yibo Ren

This article has two parts. In the first part we introduce two positivity conditions for the modified $I ¨ _{y}$ -genus on almost-complex manifolds and show that each of them implies a…

Explicit formulas for the Hattori-Stong theorem and applications

Ping Li, Wangyang Lin

We employ combinatorial techniques to present an explicit formula for the coefficients in front of Chern classes involving in the Hattori-Stong integrability conditions. We also gi…

Compactification of homology cells, Fujita's conjectures and the complex projective space

Ping Li, Thomas Peternell

We show that a compact KÃ¤hler manifold $M$ containing a smooth connected divisor $D$ such that $M ∖ D$ is a homology cell, e.g., contractible, must be projective space wit…

Hamiltonian circle action, invariant hypersurface and the complex projective space

Ping Li

Let $M$ be a $2 n$ -dimensional closed symplectic manifold admitting a Hamiltonian circle action with isolated fixed points. We show that if $M$ contains an $S^{1}$ -invariant symplecti…

Planar TurÃ¡n numbers of three configurations

Xuqing Bai, Zhipeng Gao, Ping Li

The planar TuÃ¡n number of $H$ , denoted by $e x_{P} (n, H)$ , is defined as the maximum number of edges in an $n$ -vertex $H$ -free planar graph. The exact value of $ex_{\mathc…
