Continuous Concepts Removal in Text-to-image Diffusion Models

NeurIPS 2025poster

Text-to-image diffusion models have shown an impressive ability to generate high-quality images from input textual descriptions/prompts. However, concerns have been raised about the potential for these models to create content that infringes on copyrights or depicts disturbing subject matter. Removi…

Tightening Robustness Verification of MaxPool-based Neural Networks via Minimizing the Over-Approximation Zone

CVPR 2025poster

The robustness of neural network classifiers is important in the safety-critical domain and can be quantified by robustness verification. At present, efficient and scalable verification techniques are always sound but incomplete, and thus, the improvement of verified robustness results is the key cr…

Token-Budget-Aware LLM Reasoning

ACL 2025finding

Reasoning is critical for large language models (LLMs) to excel in a wide range of tasks. While methods like Chain-of-Thought (CoT) reasoning and enhance LLM performance by decomposing problems into intermediate steps, they also incur significant overhead in token usage, leading to increased costs.…

Towards General Robustness Verification of MaxPool-based Convolutional Neural Networks via Tightening Linear Approximation

CVPR 2024poster

The robustness of convolutional neural networks (CNNs) is vital to modern AI-driven systems. It can be quantified by formal verification by providing a certified lower bound within which any perturbation does not alter the original input's classification result. It is challenging due to nonlinear co…

Backdooring Neural Code Search

ACL 2023long

Reusing off-the-shelf code snippets from online repositories is a common practice, which significantly enhances the productivity of software developers. To find desired code snippets, developers resort to code search engines through natural language queries. Neural code search models are hence behin…
