arXiv:2608. 03270v1 Announce Type: cross Abstract: GUI grounding maps natural-language instructions to click locations and is essential for reliable GUI agents.
The paper introduces MHVF, a training‑free framework for GUI grounding that uses multi‑hypothesis exploration and local visual verification with a single pretrained vision‑language model. MHVF generates spatial hypotheses from full‑screen predictions, refines them through zoomed re‑localization, and verifies candidate agreement with the instruction to resolve ambiguity. Experiments on eight benchmarks with five models show significant accuracy gains, notably improving UI‑Venus‑Ground‑7B by 4.3 pp on Mind2Web and raising Qwen2.5‑VL‑7B’s ScreenSpot‑Pro accuracy from 23.6 % to 53.6 %.
RankGround is a two‑stage framework for GUI grounding that uses a single Vision‑Language Model call per query. It introduces GroundRanker, a lightweight multimodal reranker that selects the most promising crop from a dense candidate set, trained with a two‑stage curriculum on ranking supervision data derived from existing grounding datasets. Experiments show RankGround outperforms strong baselines, achieving 1.4× faster inference and a 5.5% average improvement in localization accuracy over the second‑best method across all backbones and screen scales.

arXiv:2606. 14579v1 Announce Type: new Abstract: When applying Group Relative Policy Optimization (GRPO) for GUI Grounding, rollouts are sampled from a single screenshot view; groups often become either all failures on difficult instances or all successes on easy ones, yielding no useful relative advantage.
