GUI Agents

Why this paper matters (for operators, not just researchers) Industrial control stacks (think data center DCIM, grids, water, rail) are hostile terrain for “general” GUI agents: custom widgets, nested hierarchies, air‑gapped deployment, and actions that can actually break things. InfraMind proposes a pragmatic agentic recipe that acknowledges these constraints and designs for them. The result is a system that learns an interface before it tries to use it, then executes with auditability and guardrails. ...

The GUI Agent Bottleneck: Stuck in Sparse Feedback Training LLM-based GUI agents to complete digital tasks—such as navigating mobile apps or automating workflows—faces a fundamental limitation: reward sparsity. Traditional reward formulations (Outcome Reward Models, or ORMs) provide feedback only at the end of a trajectory. If the task fails, the agent receives zero signal, regardless of how many useful intermediate steps it took. This severely limits credit assignment and slows learning, especially in environments with long action horizons. ...
