LLM-based Embeddings: Attention Values Encode Sentence Semantics Better Than Hidden States

ICML 2026poster

Sentence representations are foundational to many Natural Language Processing (NLP) applications. While recent methods leverage Large Language Models (LLMs) to derive sentence representations, most rely on final-layer hidden states, which are optimized for next-token prediction and thus often fail t…

LogicSAGE: Neuro-Symbolic Reasoning with Socratic-Guided Enhancement

ICML 2026poster

Large Language Models (LLMs) often struggle with complex logical reasoning. Existing approaches typically rely on either purely neural reasoning in natural language or offloading to formal solvers via symbolic representations. However, both paradigms face significant limitations: while LLMs exhibit …

Environment Inference for Learning Generalizable Dynamical System

NeurIPS 2025spotlight

Data-driven methods offer efficient and robust solutions for analyzing complex dynamical systems but rely on the assumption of I.I.D. data, driving the development of generalization techniques for handling environmental differences. These techniques, however, are limited by their dependence on envir…

CFD-enabled Approach for Optimizing CPG Control Network for Underwater Soft Robotic Fish

IROS 2024poster

Central Pattern Generators (CPG) nonlinear oscillation network is being increasingly used in the control of multi-joint collaborative robots. The motion attitude of robots can be effectively adjusted by tuning parameters of the CPG neural network. However, the mapping from CPG parameters to motion a…
