Trust the Right Teacher: Quality-Aware Self-Distillation for GUI Grounding

arXiv:2606.18101v1 Announce Type: new Abstract: Graphical user interface (GUI) grounding requires vision-language models (VLMs) to identify small target elements in high-resolution screenshots and predict precise screen coordinates. On-policy self-distillation (OPSD) is a promising post-training approach for this coordinate-sensitive task, since it provides dense token-level teacher signals beyond hard coordinate labels. However, naive OPSD is not well suited to GUI grounding: OPSD evaluates the teacher on student-generated prefixes, the quality of coordinate-token teacher signals can degrade

Why this matters
Why now

The continuous advancements in vision-language models and the increasing demand for precise human-computer interaction drive the need for improved GUI grounding techniques.

Why it’s important

This research addresses a critical challenge in AI's ability to interact with and understand complex digital interfaces, directly impacting the efficacy and usability of autonomous AI systems.

What changes

The proposed 'Quality-Aware Self-Distillation' (QASD) method aims to refine how AI models learn to interpret graphical user interfaces, leading to more accurate element identification and interaction.
