FIXME: Towards End-to-End Benchmarking of LLM-Aided Design Verification

AAAI 2026technical

We introduce FIXME, the first end-to-end and large-scale benchmark for evaluating Large Language Models (LLMs) in hardware design functional verification (FV). Comprising 747 tasks derived from real-world hardware designs, FIXME spans five core FV sub-sets: specification comprehension, reference mod

Steering Representations, Safeguarding Privacy: A Cross-Modal Privacy Protection Method for Generative AI

AAAI 2026technical

Privacy concerns have long been a critical issue in AI models. With the rapid advancement of generative AI, the privacy awareness of models has drawn attention, raising new challenges for privacy protection that is independent of data and tasks. This paper introduces a novel framework for enhancing

TokenPowerBench: Benchmarking the Power Consumption of LLM Inference

AAAI 2026technical

Large language model (LLM) services now answer billions of queries per day, and industry reports show that inference, not training, accounts for more than 90% of total power consumption. However, existing benchmarks focus on either training/fine-tuning or performance of inference and provide little

Can We Steer Reasoning Direction by Thinking Intervention?

EMNLP 2025

Large Reason Models (LRMs) extend long reasoning process to solve complex tasks. However, due to the lack of fine-grained control, they often suffer from overthinking and erroneous reasoning problems, risking accuracy loss. To address this issue, we introduce Reasoning Direction Steering (RDS) to en

RepGuard: Adaptive Feature Decoupling for Robust Backdoor Defense in Large Language Models

NeurIPS 2025poster

Backdoor attacks pose a significant threat to large language models (LLMs) by embedding malicious triggers that manipulate model behavior. However, existing defenses primarily rely on prior knowledge of backdoor triggers or targets and offer only superficial mitigation strategies, thus struggling to…

Learning to Balance the Global Coherence and Informativeness in Knowledge-Grounded Dialogue Generation

ICASSP 2023accepted

Recently, knowledge-grounded dialogue has received increasing interest to render the generated responses with more useful and engaging information. However, the knowledge, locally relevant to the user’s utterance, potentially reduces the global coherence of the dialogue. Previous work mainly focuses…
