LAC: Latent Action Composition for Skeleton-based Action Segmentation

no code implementations28 Aug 2023 Di Yang, Yaohui Wang, Antitza Dantcheva, Quan Kong, Lorenzo Garattoni, Gianpiero Francesca, Francois Bremond

In this context, we propose Latent Action Composition (LAC), a novel self-supervised framework aiming at learning from synthesized composable motions for skeleton-based action segmentation.

Architecture-agnostic Iterative Black-box Certified Defense against Adversarial Patches

no code implementations18 May 2023 Di Yang, Yihao Huang, Qing Guo, Felix Juefei-Xu, Ming Hu, Yang Liu, Geguang Pu

The adversarial patch attack aims to fool image classifiers within a bounded, contiguous region of arbitrary changes, posing a real threat to computer vision systems (e. g., autonomous driving, content moderation, biometric authentication, medical imaging) in the physical world.

Latent Image Animator: Learning to Animate Images via Latent Space Navigation

no code implementations17 Mar 2022 Yaohui Wang, Di Yang, Francois Bremond, Antitza Dantcheva

Specifically, motion in generated video is constructed by linear displacement of codes in the latent space.

Latent Image Animator: Learning to animate image via latent space navigation

1 code implementation ICLR 2022 Yaohui Wang, Di Yang, Francois Bremond, Antitza Dantcheva

Deviating from such models, we here introduce Latent Image Animator (LIA), a self-supervised auto-encoder that evades need for structure representation.

Geometry and arithmetic of integrable hierarchies of KdV type. I. Integrality

no code implementations26 Jan 2021 Boris Dubrovin, Di Yang, Don Zagier

For each of the simple Lie algebras $\mathfrak{g}=A_l$, $D_l$ or $E_6$, we show that the all-genera one-point FJRW invariants of $\mathfrak{g}$-type, after multiplication by suitable products of Pochhammer symbols, are the coefficients of an algebraic generating function and hence are integral.

Aroma: Code Recommendation via Structural Code Search

2 code implementations4 Dec 2018 Sifei Luan, Di Yang, Koushik Sen, Satish Chandra

Such a tool could help programmers to extend partially written code snippets to completely implement necessary functionality, help to discover extensions to the partial code which are commonly done by other programmers, help to cross-check against similar code written by other programmers, or help to add extra code which would avoid common mistakes and errors.
