Research Papers Institution
Renmin University of China (RUC), whose Gaoling School of Artificial Intelligence is an active NLP and large-language-model research group.
AI Agents · Renmin University of China
Arbor stores research attempts in a persistent hypothesis tree, then admits changes only through held-out evaluation. It reports best held-out results on six AO tasks and 86.36% Any Medal on MLE-Bench Lite.
Mixture of Experts · Renmin University of China
MPI redesigns MoE routers by aligning router rows with expert weight directions. On 11B MoE, average benchmark accuracy rises from 40.92 to 42.76 with only 0.2% training slowdown.
Diffusion Language Models · Renmin University of China
LLaDA trains an 8B language model by masked diffusion instead of next-token prediction, matches LLaMA3 8B in in-context learning, hits 70.7 on GSM8K, and beats GPT-4o on the reversal-curse poem task.
LLM Reasoning · Renmin University of China
DelTA reweights RLVR updates so credit lands on tokens that actually separate right answers from wrong ones, lifting Qwen3-8B-Base by 3.26 and Qwen3-14B-Base by 2.62 average points over the strongest baselines.
Text Embeddings · Renmin University of China
EmbFilter reads the LLM unembedding matrix as a lens, strips the subspace that ties text embeddings to high-frequency junk tokens, and lifts zero-shot retrieval while shrinking dimensions.
