GUI-Shepherd: Reliable Process Reward and Verification for Long-Sequence GUI Tasks
Kaixiang Ji, Hao Zhong, Muzhi Zhu, Anzhou Li et autres
Autonomous agents for long-sequence Graphical User Interface tasks are hindered by sparse rewards and the intractable credit assignment problem. To address these challenges, we introduce GUI-Shepherd, a Process Reward Model that provides dense, step-by-step feedback to guide agents. GUI-Shepherd is trained on …
