For every paper on this page, at least one of the original authors has seen our plain-language explanation and engaged with it — either confirming it reads accurately or requesting corrections that we then applied. An endorsement does not mean the authors formally approve every sentence, but it does mean the explanation has passed the eyes of the people who wrote the paper.

The Thickness of Infinite Sidon Sets

Building on Erdos's proof of the existence of these numbers for Sidon sets 70 years ago, this paper establishes upper and lower bounds on the asymptotic density of γ\gamma-Golomb rulers (sets where each positive difference occurs at most γ\gamma times), proving that their size is bounded above by a term proportional to γn/logn\sqrt{\gamma n/\log n} and below by a term proportional to γn\sqrt{\gamma n}.

Invariant Reasoning Directions in Latent Trajectories of Language Models

This paper introduces Trajectory-Invariant Latent Refinement (TILR), a training-free framework that identifies and manipulates stable, low-rank invariant directions within language model latent trajectories to significantly improve reasoning consistency and reduce sensitivity to paraphrasing and perturbations without sacrificing accuracy.

Towards Evaluating Data Priors for Tabular Foundation Models

This paper introduces a unified framework to independently evaluate and compare data-generating priors for tabular foundation models by training identical architectures on tasks derived from various priors, revealing that different priors significantly influence downstream performance and consistency beyond mere data-level similarity.

Deterministic Decisions for High-Stakes AI. A Zero-Egress Pipeline with the Deployability of RAG and the Accuracy of Machine Learning

This paper identifies and quantifies "intervention bias" in zero-shot LLM educational advisors, which erroneously recommend unnecessary actions compared to an optimal oracle, and demonstrates that supervised policy learning using Decision Transformers or XGBoost effectively eliminates this bias while achieving high accuracy and low-latency decisions suitable for high-stakes deployment.

How Far Can You Get Without a GPU? A Systematic Benchmark of Lightweight Hallucination Detection Across Question Answering, Dialogue, and Summarisation

This paper systematically benchmarks five lightweight, CPU-feasible hallucination detection methods across question answering, dialogue, and summarization tasks, revealing that performance is highly task-dependent with ensemble methods excelling in QA, NLI detectors leading in dialogue, and all approaches failing significantly on summarization.

Evidence-Informed LLM Beliefs for Continual Scientific Discovery

This paper introduces an evidence-informed framework for continual scientific discovery with LLMs that replaces static Bayesian surprise with non-stationary, belief-updated surprisal and employs filtering and diversity maximization to eliminate spurious rewards, thereby significantly improving hypothesis exploration across multiple domains.

SurrogateShield: Beyond Redaction for High-Utility, Privacy-Preserving LLM Interactions

SurrogateShield is a client-side proxy that enhances privacy-preserving LLM interactions by replacing detected PII with locally generated, type-consistent surrogate values before transmission and restoring the originals in responses, thereby eliminating real PII exposure while significantly improving semantic utility compared to traditional redaction methods.
