Description

Python computations in science and engineering (pycse) - helps with scientific computing tasks including nonlinear regression, uncertainty quantification, design of experiments (DOE), Latin hypercube sampling, surface response modeling, and neural network-based UQ with DPOSE. Use when working with numerical optimization, data fitting, experimental design, or uncertainty analysis.

pycse - Python Computations in Science and Engineering

pycse is a comprehensive library for scientific computing, data analysis, and uncertainty quantification in Python.

1. Nonlinear Regression and Curve Fitting

• nlinfit: Nonlinear least squares fitting with uncertainty quantification • regress: Linear regression with statistics • Supports parameter uncertainty estimation and confidence intervals

2. Design of Experiments (DOE)

• Latin Hypercube Sampling (LHC): Space-filling designs for efficient parameter exploration • Surface Response Modeling: Fit polynomial response surfaces to experimental data • Useful for optimizing experimental conditions with minimal trials

3. Uncertainty Quantification with DPOSE

• DPOSE (Direct Propagation of Shallow Ensembles): Neural network ensemble for UQ • Provides per-sample uncertainty estimates (heteroscedastic) • Handles gaps, extrapolation, and nonlinear relationships • Trained using CRPS or NLL loss for calibrated uncertainties
