From Concept Alignment to Causal Grounding: An Intervention Test of Chain-of-Thought Faithfulness
Qianli Wang, Yilong Wang, Dennis Wei +5
Chain-of-thought (CoT) can sound plausible yet be unfaithful to the model's underlying reasoning. Most prior work probes CoT faithfulness through input--output behavior or input at…
iFlip: Iterative Feedback-driven Counterfactual Example Refinement
Yilong Wang, Qianli Wang, Nils Feldhus
Counterfactual examples are minimal edits to an input that alter a model's prediction. They are widely employed in explainable AI to probe model behavior and in natural language pr…
ViPSN 2.0: A Reconfigurable Battery-free IoT Platform for Vibration Energy Harvesting
Xin Li, Mianxin Xiao, Xi Shen +22
Vibration energy harvesting is a promising solution for powering battery-free IoT systems; however, the instability of ambient vibrations presents significant challenges, such as l…
Alterfold Theory and Topological Modular Invariance
Zhengwei Liu, Shuang Ming, Yilong Wang +1
We propose a topological paradigm in alterfold topological quantum field theory to explore various concepts, including modular invariants, -induction and connections in Morita c…
Alterfold Topological Quantum Field Theory
Zhengwei Liu, Shuang Ming, Yilong Wang +1
We introduce the 3-alterfold topological quantum field theory (TQFT) by extending the quantum invariant of 3-alterfolds. The bases of the TQFT are explicitly characterized and the…
