1. **[ToxiGen: A Large-Scale Machine-Generated Dataset for Adversarial and Implicit Hate Speech Detection](https://md.research.elamur.ai/free/en/papers/hartvigsen-2022-toxigen-large-scale-machine-generated/)** *(2022 · 578 citations)* Hate speech classifiers often learn a shortcut: they treat any mention of a minority group as a sign of toxicity.
2. **[Interpretable Unified Language Checking](https://md.research.elamur.ai/free/en/papers/zhang-2023-interpretable-unified-language-checking/)** *(2023 · 32 citations)* Harmful text, whether written by people or produced by LLMs, can be wrong in different ways: it may be false, stereotyping, or hateful.
3. **[Math Neurosurgery: Isolating Language Models' Math Reasoning Abilities Using Only Forward Passes](https://md.research.elamur.ai/free/en/papers/christ-2025-math-neurosurgery-isolating-language-models/)** *(2025 · 7 citations)* The paper asks whether mathematical reasoning in large language models is tied to a separable set of parameters, and whether that set can be located cheaply.
4. **[Disparities in LLM Reasoning Accuracy and Explanations: A Case Study on African American English](https://md.research.elamur.ai/free/en/papers/zhou-2025-disparities-llm-reasoning-accuracy-explanations/)** *(2025 · 6 citations)* The paper asks whether large language models reason as well, and explain themselves as well, when a question is written in African American English (AAE) as when it is written in Standard American English (SAE).
5. **[Inferring Events from Time Series using Language Models](https://md.research.elamur.ai/free/en/papers/tan-2026-inferring-events-time-series-language/)** *(2026 · 1 citation)* The paper asks whether large language models can work backwards from a numeric time series to the real-world events that likely produced it.
