FrontierScience: Evaluating AI's Ability to Perform Expert-Level Scientific Tasks

Miles Wang, Robi Lin, Kat Hu +4

We introduce FrontierScience, a benchmark evaluating expert-level scientific reasoning in frontier language models. Recent model progress has nearly saturated existing science benc…

The Unified Cognitive Consciousness Theory for Language Models: Anchoring Semantics, Thresholds of Activation, and Emergent Reasoning

Edward Y. Chang, Zeyneb N. Kaya, Ethan Chang

We propose semantic anchoring, a unified account of how large language models turn pretrained capacity into goal-directed behavior: external structure (in-context examples, retriev…

VMDT: Decoding the Trustworthiness of Video Foundation Models

Yujin Potter, Zhun Wang, Nicholas Crispino +11

As foundation models become more sophisticated, ensuring their trustworthiness becomes increasingly critical; yet, unlike text and image, the video modality still lacks comprehensi…

Inverse-Free Wilson Loops for Transformers: A Practical Diagnostic for Invariance and Order Sensitivity

Edward Y. Chang, Ethan Y. Chang

Large language models can change answers under harmless edits that matter in practice: RAG outputs flip when passages are reordered, fine-tuning erodes invariances learned at pretr…

Multi-Agent Collaborative Intelligence: Dual-Dial Control for Reliable LLM Reasoning

Edward Y. Chang, Ethan Y. Chang

Multi-agent debate often wastes compute by using a fixed adversarial stance, aggregating without deliberation, or stopping on heuristics. We introduce MACI, an active controller wi…

Knowledge Tagging with Large Language Model based Multi-Agent System

Hang Li, Tianlong Xu, Ethan Chang +1

Knowledge tagging for questions is vital in modern intelligent educational applications, including learning progress diagnosis, practice question recommendations, and course conten…
