Multimodal Concept Bottleneck Models

Tongqing Shi, Ge Yan, Tuomas Oikarinen +1

Concept Bottleneck Models (CBMs) enhance the interpretability of deep learning networks by aligning the features extracted from images with natural concepts. However, existing CBMs…

LLM Agents Already Know When to Call Tools -- Even Without Reasoning

Chung-En Sun, Linbo Liu, Ge Yan +2

Tool-augmented LLM agents tend to call tools indiscriminately, even when the model can answer directly. Each unnecessary call wastes API fees and latency, yet no existing benchmark…

Steer2Edit: From Activation Steering to Component-Level Editing

Chung-En Sun, Ge Yan, Zimo Wang +1

Steering methods influence Large Language Model behavior by identifying semantic directions in hidden representations, but are typically realized through inference-time activation…

Distance Marching for Generative Modeling

Zimo Wang, Ishit Mehta, Haolin Lu +4

Time-unconditional generative models learn time-independent denoising vector fields. But without time conditioning, the same noisy input may correspond to multiple noise levels and…

Faithful and Stable Neuron Explanations for Trustworthy Mechanistic Interpretability

Ge Yan, Tuomas Oikarinen, Tsui-Wei +1

Neuron identification is a popular tool in mechanistic interpretability, aiming to uncover the human-interpretable concepts represented by individual neurons in deep networks. Whil…

ReflCtrl: Controlling LLM Reflection via Representation Engineering

Ge Yan, Chung-En Sun, Tsui-Wei +1

Large language models (LLMs) with Chain-of-Thought (CoT) reasoning have achieved strong performance across diverse tasks, including mathematics, coding, and general reasoning. A di…
