An Information-Theoretic Framework for Out-of-Distribution Generalization

no code implementations29 Mar 2024 Wenliang Liu, Guanding Yu, Lele Wang, Renjie Liao

We study the Out-of-Distribution (OOD) generalization in machine learning and propose a general framework that provides information-theoretic generalization bounds.

Joint Generative Modeling of Scene Graphs and Images via Diffusion Models

no code implementations2 Jan 2024 Bicheng Xu, Qi Yan, Renjie Liao, Lele Wang, Leonid Sigal

While previous works have explored image generation conditioned on scene graphs or layouts, our task is distinctive and important as it involves generating scene graphs themselves unconditionally from noise, enabling efficient and interpretable control for image generation.

Noisy Computing of the $\mathsf{OR}$ and $\mathsf{MAX}$ Functions

no code implementations7 Sep 2023 Banghua Zhu, Ziao Wang, Nadim Ghaddar, Jiantao Jiao, Lele Wang

We consider the problem of computing a function of $n$ variables using noisy queries, where each query is incorrect with some fixed and known probability $p \in (0, 1/2)$.

SwinGNN: Rethinking Permutation Invariance in Diffusion Models for Graph Generation

1 code implementation4 Jul 2023 Qi Yan, Zhengyang Liang, Yang song, Renjie Liao, Lele Wang

Diffusion models based on permutation-equivariant networks can learn permutation-invariant distributions for graph data.

On the Optimal Bounds for Noisy Computing

no code implementations21 Jun 2023 Banghua Zhu, Ziao Wang, Nadim Ghaddar, Jiantao Jiao, Lele Wang

However, the upper and lower bounds do not match in terms of the dependence on $\delta$ and $p$.

Specformer: Spectral Graph Neural Networks Meet Transformers

1 code implementation2 Mar 2023 Deyu Bo, Chuan Shi, Lele Wang, Renjie Liao

To tackle these issues, we introduce Specformer, which effectively encodes the set of all eigenvalues and performs self-attention in the spectral domain, leading to a learnable set-to-set spectral filter.

Adversarial Ensemble Training by Jointly Learning Label Dependencies and Member Models

1 code implementation29 Jun 2022 Lele Wang, Bin Liu

In this paper, we propose a novel adversarial en-semble training approach that jointly learns the label dependencies and member models.

Soft BIBD and Product Gradient Codes

no code implementations11 May 2021 Animesh Sakorikar, Lele Wang

In this paper, we aim to overcome such limitations and construct gradient codes which exist for a wide range of system parameters while retaining the superior performance of BIBD gradient codes.
