1. MAPO: Advancing Multilingual Reasoning through Multilingual-Alignment-as-Preference Optimization (2024 · 59 citations)
   Large language models tend to solve math word problems much better in English than in other languages, mainly because their training data is skewed toward English.
2. CAFES: A Collaborative Multi-Agent Framework for Multi-Granular Multimodal Essay Scoring (2026 · 4 citations)
   Multimodal writing tasks ask students to argue from images such as charts. Scoring them automatically is hard. Classic AES systems depend on handcrafted features and cannot process images. Single-MLLM scorers tend to invent justifications and grade more harshly than human raters. CAFES addresses this by dividing…
3. Mixture of Heterogeneous Grouped Experts for Language Modeling (2026)
   Standard Mixture-of-Experts (MoE) language models use experts of one fixed size, so every token receives the same compute regardless of how hard it is to predict.
4. Probing the Plasticity and Correlation of LLM Value Systems: LLM Value Rankings are Not Stable (2026)
   Earlier work found that different LLMs rank their values in similar ways. This paper asks whether those rankings stay fixed when the model is pushed by its context, and whether some values tend to shift together. The authors build on the LITMUSVALUES setup. Models face two-action dilemmas, each action tied to one of…
