ProtocolMatch: Protocol-Dependent Model Selection for Scientific Dynamics Forecasting
Lu Wei, Yufeng Wang, Haibin Ling
Scientific dynamics forecasting is often framed as an architecture choice, although deployment is also determined by observed history, rollout feedback, compute budget, physical ob…
A Comparative Study of Evaluation Metrics for Long-Document Financial Narrative Summarization with Transformers
Nadhem Zmandar, Mo El-Haj, Paul Rayson
There are more than 2,000 listed companies on the UK's London Stock Exchange, divided into 11 sectors who are required to communicate their financial results at least twice in a si…
Apparent Compression, Real Stability: The Intrinsic Dimension of Learning a Quantum Wavefunction
Lu Wei, Yufeng Wang, Chenfeng Cao +1
How many directions in weight space does training need? The intrinsic dimension answers this with the smallest number of random directions in which training still reaches a target…
AG-CoT: Verified Algorithmic Traces for LLM Program Synthesis on Clifford Circuits
Lu Wei, Yufeng Wang, Chenfeng Cao +2
Scientific code generation can produce executable programs that fail to compute the intended scientific object. We study this problem in language-model synthesis of Clifford circui…
Stable and Counterfactually Robust Physical World Models from Imposed Structure and Learned Physics
Yufeng Wang, Parivesh Priye, Lu Wei +1
A world model learns to forecast how a physical system evolves from recorded trajectories, yet the systems it imitates obey physical laws that are neither fully supplied nor reliab…
Available Guardrails: Certifying Selective Prediction across ML Systems
Parivesh Priye, Yufeng Wang, Haibin Ling +1
A selective predictor acts as a safety gate: it returns an output only when the prediction appears sufficiently trustworthy. Deployments increasingly require this reliability to be…
Conservation Buys Stability and Factoring Buys Counterfactuals in Physical World Models
Yufeng Wang, Parivesh Priye, Lu Wei +1
A learned simulator can reproduce its training conditions accurately yet fail in two distinct ways once those conditions change. Over long rollouts, small errors accumulate until t…
Grounding Spatial Relations in a Compact World Model: Instruction Leakage and a Goal-Free Dynamics Fix
Yufeng Wang, Lu Wei, Haibin Ling
Compact world models that condition on a language goal promise to ground relations such as ``put the red block left of the blue block'' using a sparse set of explicit \emph{referen…
Conservative Discrete Structure Stabilizes Autoregressive Rollouts in a 1D Drift Diffusion Poisson Benchmark
Yufeng Wang, Lu Wei, Haibin Ling
Learned plasma transport surrogates can match short horizon states while failing over long rollouts because charge accounting, density admissibility, and Poisson compatible field r…
How well can off-the-shelf LLMs elucidate molecular structures from mass spectra using chain-of-thought reasoning?
Yufeng Wang, Lu Wei, Lin Liu +2
Mass spectrometry (MS) is a powerful analytical technique for identifying small molecules, yet determining complete molecular structures directly from tandem mass spectra (MS/MS) r…
Retrieval as a Decision: Training-Free Adaptive Gating for Efficient RAG
Yufeng Wang, Lu wei, Haibin Ling
Retrieval-Augmented Generation (RAG) improves factuality but retrieving for every query often hurts quality while inflating tokens and latency. We propose Training-free Adaptive Re…
SVQA-R1: Reinforcing Spatial Reasoning in MLLMs via View-Consistent Reward Optimization
Peiyao Wang, Haibin Ling
Spatial reasoning remains a critical yet underdeveloped capability in existing vision-language models (VLMs), especially for Spatial Visual Question Answering (Spatial VQA) tasks t…
Spectra-to-Structure and Structure-to-Spectra Inference Across the Periodic Table
Yufeng Wang, Peiyao Wang, Lu Wei +4
X-ray Absorption Spectroscopy (XAS) is a powerful technique for probing local atomic environments, yet its interpretation remains limited by the need for expert-driven analysis, co…
XDIP: A Curated X-ray Absorption Spectrum Dataset for Iron-Containing Proteins
Yufeng Wang, Peiyao Wang, Lu Wei +6
Earth-abundant iron is an essential metal in regulating the structure and function of proteins. This study presents the development of a comprehensive X-ray Absorption Spectroscopy…
Variational Transformer Ansatz for the Density Operator of Steady States in Dissipative Quantum Many-Body Systems
Lu Wei, Zhian Jia, Yufeng Wang +2
The transformer architecture, known for capturing long-range dependencies and intricate patterns, has extended beyond natural language processing. Recently, it has attracted signif…
