Plain-Language Brief

Researchers introduce a new method called PEEU to improve the task planning capabilities of small, open-source multimodal web agents that assist humans in operating repetitive graphical user interface (GUI) tasks. These agents often struggle with weak planning and limited cross-website generalization compared to commercial large models. The PEEU method autonomously explores environments to discover experiences and utilizes hindsight experience to synthesize high-level training data, which is crucial for the out-of-distribution (OOD) planning abilities of these small models. The researchers also propose a framework called TDHAF for analyzing the generalization behaviors that drive this performance.

What the Document Says

  • The paper discusses the limitations of small, open-source MLLMs in assisting humans with GUI tasks, specifically weak planning and limited cross-website generalization compared to commercial large models.
  • The authors introduce the PEEU method for addressing these limitations. PEEU autonomously explores environments to discover experiences and utilizes hindsight experience to synthesize high-level training data.
  • The TDHAF framework is proposed for quantitative analysis of the generalization behaviors driving this performance.
  • The research reveals that mastering low-level atomic skills does not guarantee high-level planning competence, while high-level task training yields stronger out-of-distribution (OOD) generalization.
  • Experiments on real-world benchmarks show the superior effectiveness of PEEU: their 7B model achieves 30.6% accuracy, outperforming a much larger Qwen2.5-VL-32B model.

Raw Abstract / Excerpt

Multimodal web agents can assist humans in operating repetitive GUI tasks, where effective task planning is essential for decomposing complex tasks into executable actions. While small open source MLLMs are cost efficient and privacy preserving compared with commercial large models, they suffer from weak planning and limited cross website generalization. To address these limitations, we introduce the planning experience exploration and utilization (PEEU) method, which autonomously explores environments to discover experiences and utilizes hindsight experience to synthesize strictly aligned, high level training data. To quantitatively analyze the generalization behaviors driving this performance, we propose the task decomposition hierarchical analysis framework (TDHAF) to systematically study compositional generalization across three task granularities: low, middle and high levels. Our analysis reveals that mastering low level atomic skills does not guarantee high level planning competence, while high level task training yields stronger OOD generalization. Experiments on real world benchmarks demonstrate PEEU's superior effectiveness: our 7B model achieves 30.6% accuracy, outperforming the much larger Qwen2.5-VL-32B model. These demonstrate constructing hindsight high level tasks and leveraging experiences is crucial for OOD planning abilities of small MLLMs.
