Research Papers Institution
Leading Chinese research university in Hangzhou with strong AI, NLP, and machine learning groups.
Vision Foundation Models · Zhejiang University
A frozen-feature probe pits VLMs against video-generation models on spatial tasks. VLMs win semantics (92.08 mAP vs 69.89), video models win geometry (0.527 camera AUC vs 0.330), and a naive concat of the two beats both.
MemDreamer turns hours-long video QA into agentic retrieval over a 3-tier graph memory, lifting LVBench from 78.2 to 90.7 (+12.5) while the reasoning model reads ~6K tokens instead of 240K-784K.
Reinforcement Learning · Zhejiang University
N-GRPO perturbs rollout embeddings with semantic neighbors, lifting DeepSeek-R1-Distill-Qwen-1.5B average Pass@32 to 79.17 and AIME25 Pass@32 to 50.28.
AI Agents · Zhejiang University
WeaveBench tests 114 real hybrid GUI plus CLI tasks; the best frontier pairing reaches only 41.2% PassRate, and final-only grading overstates GPT-5.5 by 20.2 points.
Vision-Language-Action · Zhejiang University
LabVLA trains a Qwen3-VL-4B backbone plus DiT action expert on laboratory workflows and reports 71.1% ID and 70.0% OOD success on LabUtopia.
MiniMax Sparse Attention keeps only 2,048 selected KV tokens per query group and reports 28.4x lower attention FLOPs plus 14.2x prefill speedup at 1M context.
SkillAdaptor edits an agent's skill library from failed trajectories without touching model weights, lifting WebShop score +2.3 and PinchBench +1.5 over the frozen backbone.
StreamMA pipes each reasoning step to the next agent the moment it is written, not after the full chain. Across 8 benchmarks it gains +7.3 pp on average (max +22.4 pp on HMMT 2026) and runs up to 26.9x faster.
Speech Synthesis · Zhejiang University
SwanSphere streams first-order ambisonic audio synced to video or text, emitting its first chunk in 0.21s while cutting Frechet Distance to 120.28 vs OmniAudio's 157.67. Quality without waiting for the whole clip.
AI Agents · Zhejiang University
SDAR adds a gated, token-level self-distillation signal from a skill-augmented teacher on top of GRPO, lifting multi-turn agents by up to +10.2 points on WebShop and +9.4 on ALFWorld for small Qwen models.
