Compositional Embedding Architecture for Physical Field Prediction in Componentized Aerospace Systems
Read the original on arXiv Machine Learning →The paper introduces the Tree-Structured Factor Composition Network (TFCN), a surrogate model that decomposes spacecraft thermal configurations into reusable local physical factors and learns their global temperature-field response via a tree-structured composition module. Trained on configurations with up to 15 heat-generating components, TFCN is evaluated on unseen setups with 16–25 components, achieving out-of-distribution RMSE reductions of 65.6% and 33.6% compared to the best baseline for prescribed-temperature and radiative-flux boundary conditions, respectively. These results demonstrate that TFCN can reliably predict temperature fields across varying component counts, enabling efficient rapid evaluation and large-scale screening in spacecraft thermal design.
