Evidencepartial
introduce StateFactory, a factorized representation method that transforms unstructured observations into a hierarchical object-attribute structure using language models
Implicationpartial
Directly stated in abstract as the core method description
Verificationpartial
partial
Evidencepartial
This structured representation allows rewards to be estimated naturally as the semantic similarity between the current state and the goal state under hierarchical constraint
Implicationpartial
Directly stated in abstract as a key technical mechanism
Verificationpartial

Evidencepartial
achieving 60% and 8% lower EPIC distance, respectively
Implicationpartial
Direct numeric result stated in abstract with specific metric
Verificationpartial

Evidencepartial
yielding success rate gains of +21.64% on AlfWorld and +12.40% on ScienceWorld over reactive system-1 policies
Implicationpartial

Evidencepartial
yielding success rate gains of +21.64% on AlfWorld and +12.40% on ScienceWorld over reactive system-1 policies
Implicationpartial
Direct numeric result stated in abstract with specific benchmark
Verificationpartial
partial
Evidencepartial
the compact representation structure induced by StateFactory enables strong reward generalization capabilities
Implicationpartial
Directly stated in abstract as a key benefit, though 'strong' is qualitative
Verificationpartial
partial
Evidencepartial
Supervised learning of reward models could introduce biases inherent to training data, limiting generalization to novel goals and environments
Implicationpartial
Directly stated as motivation for the research, though presented as a general limitation of existing approaches
Verificationpartial
partial
Evidencepartial
Our method shows promising zero-shot results against both VLWM-critic and LLM-as-a-Judge reward models, achieving 60% and 8% lower EPIC distance, respectively
Implicationpartial
Direct numeric result stated in abstract with specific comparison
