Harness In-Context Operator Learning with Chain of Operators
Researchers have developed a new framework called Chain of Operators (CHOP) to improve the generalization capabilities of In-Context Operator Networks (ICON). ICON models learn operators from prompts but can struggle with out-of-distribution tasks. CHOP addresses this by constructing a chain of elementary transformations and the frozen ICON, allowing it to adapt to new operator tasks without parameter updates. Experiments show CHOP reduces inference error and maintains interpretability, even generalizing across different partial differential equation families. AI
