ManiUnit: A Manipulation Skill Dataset and Benchmark for Long-Horizon Tasks

Guoting Wei, Dawei Yan, Xia Yuan وآخرون · 2026

Long-horizon mobile manipulation requires a robot to navigate multi-room environments and execute a sequence of manipulation skills under a single natural language instruction. Learning and evaluating these skills present three challenges: similar observations under a fixed task instruction may make skill selection amb …

SubRot: Signed Gradient Subspace Calibration for VLM Rotation Quantization

Zhenhao Shang, Haizhao Jing, Haokui Zhang وآخرون · 2026

Post-training quantization reduces the deployment cost of vision-language models (VLMs), but preserving multimodal capabilities at low bit widths remains challenging. Existing methods rely on modality- or token-level gradient statistics, which are susceptible to cross-sample variations in visual-to-textual token ratios …
