SciML in the Wild: A Diagnostic Study of When Structural Priors Help and When They Hurt

arXiv:2607. 09684v1 Announce Type: cross Abstract: Scientific Machine Learning (SciML) methods such as Neural Ordinary Differential Equations (NODEs), Physics-Informed Neural Networks (PINNs), and Universal Differential Equations (UDEs) are most effective when structural priors reflect reliable governing dynamics.

AnalysisBank: An Expert Analysis Pattern Library for Financial Report Generation

AnalysisBank is a library that captures expert financial analysis by pairing data signals with analytical moves and the corresponding expert text spans. The system matches input signals to these library entries during inference, enabling the generation of reports that are grounded in data-derived insights rather than generic structural templates. Experiments on financial benchmarks show that AnalysisBank produces 1.7–3.7 times more novel, data‑grounded insights than structural baselines, and the approach also transfers to scientific writing.

GroupSegment-SHAP: Shapley Value Explanations with Group-Segment Players for Multivariate Time Series

GroupSegment-SHAP (GS‑SHAP) introduces explanatory units called group‑segment players that capture cross‑variable dependence and distribution shifts over time in multivariate time‑series models. By attributing Shapley values to these units, GS‑SHAP preserves joint structural signals that traditional time‑series SHAP variants fragment. Experiments on human activity recognition, power‑system forecasting, medical signal analysis, and financial time series show that GS‑SHAP improves deletion‑based faithfulness by about 1.7× and reduces runtime by roughly 40% compared to existing baselines, while a financial case study demonstrates its ability to reveal interpretable multivariate‑temporal interactions during high‑volatility periods.
