Graph Domain Adaptation via Homophily-Agnostic Reconstructing Structure

AAAI 2026technical

Graph Domain Adaptation (GDA) transfers knowledge from labeled source graphs to unlabeled target graphs, addressing the challenge of label scarcity. However, existing GDA methods typically assume that both source and target graphs exhibit homophily, leading existing methods to perform poorly when he

When Priors Backfire: On the Vulnerability of Unlearnable Examples to Pretraining

ICLR 2026poster

Unlearnable Examples (UEs) are introduced as a data protection strategy that generates imperceptible perturbations to mislead models into learning spurious correlations rather than real semantics. In this paper, we reveal a fundamental vulnerability of UEs that emerges when learning starts from a pr…

MABR: Multilayer Adversarial Bias Removal Without Prior Bias Knowledge

AAAI 2025technical

Models trained on real-world data often mirror and exacerbate existing social biases. Traditional methods for mitigating these biases typically require prior knowledge of the specific biases to be addressed, and the social groups associated with each instance. In this paper, we introduce a novel adv…

On the Benefits of Attribute-Driven Graph Domain Adaptation

ICLR 2025poster

Graph Domain Adaptation (GDA) addresses a pressing challenge in cross-network learning, particularly pertinent due to the absence of labeled data in real-world graph datasets. Recent studies attempted to learn domain invariant representations by eliminating structural shifts between graphs. In this…

Revisiting Source-Free Domain Adaptation: a New Perspective via Uncertainty Control

ICLR 2025poster

Source-Free Domain Adaptation (SFDA) seeks to adapt a pre-trained source model to the target domain using only unlabeled target data, without access to the original source data. While current state-of-the-art (SOTA) methods rely on leveraging weak supervision from the source model to extract reliabl…

Textualize Visual Prompt for Image Editing via Diffusion Bridge

AAAI 2025technical

Visual prompt, a pair of before-and-after edited images, can convey indescribable imagery transformations and prosper in image editing. However, current visual prompt methods rely on a pretrained text-guided image-to-image generative model that requires a triplet of text, before, and after images fo…

Unveil Inversion and Invariance in Flow Transformer for Versatile Image Editing

CVPR 2025poster

Leveraging the large generative prior of the flow transformer for tuning-free image editing requires authentic inversion to project the image into the model's domain and a flexible invariance control mechanism to preserve non-target contents. However, the prevailing diffusion inversion performs defi…

ZETA: Leveraging $Z$-order Curves for Efficient Top-$k$ Attention

ICLR 2025poster

Over recent years, the Transformer has become a fundamental building block for sequence modeling architectures. Yet at its core is the use of self-attention, whose memory and computational cost grow quadratically with the sequence length $N$, rendering it prohibitively expensive for long sequences.…
