LexInstructEval: Lexical Instruction Following Evaluation for Large Language Models

AAAI 2026technical

The ability of Large Language Models (LLMs) to precisely follow complex and fine-grained lexical instructions is a cornerstone of their utility and controllability. However, evaluating this capability remains a significant challenge. Current methods either rely on subjective and costly human evaluat

Thinking on the Fly: Test-Time Reasoning Enhancement via Latent Thought Policy Optimization

ICLR 2026poster

Recent advancements in Large Language Models (LLMs) have shifted from explicit Chain-of-Thought (CoT) reasoning to more efficient latent reasoning, where intermediate thoughts are represented as vectors rather than text. However, latent reasoning can be brittle on challenging, out-of-distribution ta…

An Empirical Study of LLM Reasoning Ability Under Strict Output Length Constraint

EMNLP 2025

Recent work has demonstrated the remarkable potential of Large Language Models (LLMs) in test-time scaling. By making models think before answering, they are able to achieve much higher accuracy with extra inference computation.However, in many real-world scenarios, models are used under time constr

An End-to-End Graph-Guided Spatiotemporal Model for Adaptive Frame-Level Facial Affect Analysis in the Wild

ICASSP 2025accepted

Human emotional states in real life are varied and complex. It is difficult for existing methods to capture robust facial expression features dynamically, especially in a large head pose and occlusion. In this paper, a novel end-to-end graph-guided spatiotemporal convolutional network (GSTCN) is pro…

SEE: Semantically Aligned EEG-to-Text Translation

ICASSP 2025accepted

Decoding neurophysiological signals into language is of great research interest within brain-computer interface (BCI) applications. Electroencephalography (EEG), known for its non-invasiveness, ease of use, and cost-effectiveness, has been a popular method in this field. However, current EEG-to-Text…

Concept2Box: Joint Geometric Embeddings for Learning Two-View Knowledge Graphs

ACL 2023findings

Knowledge graph embeddings (KGE) have been extensively studied to embed large-scale relational data for many real-world applications. Existing methods have long ignored the fact many KGs contain two fundamentally different views: high-level ontology-view concepts and fine-grained instance-view entit…
