Research Timeline

2026
LACUNA: Safe Agents as Recursive Program Holes

The paper introduces LACUNA, a novel programming model that allows LLM agents to write code that shapes the runtime environment while maintaining strong type-checking safety guarantees.

Semantic Optimal Transport for Sparse Autoencoder Feature Matching and Circuit Compression

The paper introduces a distributional framework using Wasserstein distance to unify the semantic comparison of sparse autoencoder features across different layers and to automatically compress large feature circuits into interpretable supernodes.

MolLingo: Molecule-Native Representations for LLM-Powered Scientific Agents

MolLingo is a multi-agent system that significantly improves automated molecular design by integrating domain-specific chemical reasoning and structural context into LLMs, outperforming state-of-the-art models on multiple benchmarks.

FPMoE: A Sparse Mixture-of-Experts Approach to Functional Code Generation

FPMoE introduces a sparse Mixture-of-Experts (MoE) architecture to improve functional code generation across multiple functional programming languages, achieving state-of-the-art performance with fewer parameters.

Physics Is All You Need? A Case Study in Physicist-Supervised AI Development of Scientific Software

This case study demonstrates that in complex scientific software development, human domain expertise and careful supervision are more critical to ensuring the trustworthiness of AI-generated code than the raw capability of the AI model itself.

Neural Network Verification using Partial Multi-Neuron Relaxation

The paper introduces partial multi-neuron relaxation, a novel verification technique that selectively computes tight linear bounds for a small subset of neurons to improve the efficiency and tightness of neural network safety verification.

Croissant Tasks: A Metadata Format for Reproducible Machine Learning Evaluations

The paper introduces Croissant Tasks, a declarative metadata format designed to achieve conceptual reproducibility in machine learning by abstracting problem specifications from brittle implementation details.

Wait! There's a Way Out: A Decision Mechanism for Forecasting Conversational Derailment

The paper proposes a novel decision mechanism that decouples the decision to issue an alert from the raw likelihood of conversational derailment, significantly reducing false positives by simulating potential recovery paths.

Refining Word-Based Grammatical Error Annotation for L2 Korean

This paper refines word-based grammatical error annotation for L2 Korean by adapting existing resources to better reflect Korean morphology and error types, improving the evaluation of Korean Grammatical Error Correction (K-GEC) systems.

Social welfare optimisation under institutional reward and punishment

This paper introduces a welfare-centric framework for designing institutional incentives, showing that optimizing for total social welfare often requires different incentive levels than those optimized for cost or cooperation frequency.

CodeCytos: AI-assisted spatial molecular imaging analysis via code-augmented agent action space

CodeCytos is a novel coding-based reasoning agent framework that enables dynamic, programmable interaction with spatial molecular imaging data, significantly improving the automation and customization of complex tissue analysis.

NICE: A Framework for Declarative and Machine-Checkable Vulnerability Reproduction

The paper introduces NICE, a declarative framework that uses NixOS to build and automatically validate reproducible environments for demonstrating software vulnerabilities (CVEs), thereby improving the reliability and shareability of security research.

Don't Read Everything: A Curvature-Conditioned Query for Linear Attention

The paper introduces Curvature-Conditioned Query (CCQ), a novel read-time contraction mechanism that improves linear attention's performance on long-context and retrieval tasks by incorporating the geometry of the softmax function.

Multilingual Idioms in Sentences and Conversations Across High-, Medium-, and Low-Resource Languages

The paper introduces MIDI, a novel multilingual dataset that embeds idioms in realistic sentence and conversational contexts across diverse resource levels, revealing that idiom comprehension is significantly harder in low-resource languages and that literal interpretations pose a greater challenge than figurative ones.

TriAlign: Towards Universal Truth Consistency in Personalized LLM Alignment

The paper proposes TriAlign, a novel multi-agent reinforcement learning framework that achieves universal truth consistency across social groups in personalized LLMs while maintaining high accuracy and personalization.

ProbMoE: Differentiable Probabilistic Routing for Mixture-of-Experts

The paper introduces ProbMoE, a probabilistic routing framework that tackles the non-differentiability of top-$k$ routing in Mixture-of-Experts (MoE) models, achieving strong performance with improved expert utilization.

Implementation and Optimization of HQC Decoding on NPU-Integrated Devices

This paper optimizes the decoding of Hamming Quasi-Cyclic (HQC) codes for post-quantum cryptography on NPU-integrated mobile devices by redesigning the kernels to leverage the Hexagon Vector eXtensions (HVX), achieving significant reductions in latency and energy consumption.

Mitigating Bias in Locally Constrained Decoding via Tractable Proposals

The paper proposes a novel probabilistic globally constrained decoding (P-GCD) method that efficiently constructs proposals for locally constrained decoding, significantly improving convergence speed and performance compared to existing approaches.

Implementation and Optimization of HQC Decoding on NPU-Integrated Devices

This paper optimizes the decoding of Hamming Quasi-Cyclic (HQC) codes for post-quantum cryptography on NPU-integrated mobile devices by redesigning the core kernels to leverage the Hexagon Vector eXtensions (HVX) backend.

Towards Worst-case Hardness for Low-Noise LPN

The paper presents a new worst-case to average-case reduction for the Learning Parity with Noise (LPN) problem, achieving hardness for inverse-polynomial noise rates previously unattainable.
