SEAM Surrogate Modeling and Design Optimization Course Material

Overview

This repository contains materials for an introductory course on "Surrogate Modeling and Design Optimization," originally developed for the Shared Education in Artificial intelligence and Machine learning (SEAM) professional development program at Lawrence Livermore National Laboratory (LLNL). It features the surmod Python package, which implements core techniques including Feedforward Neural Networks (FFNNs) and Gaussian Processes (GPs) as surrogates, basic Bayesian Optimization (BO) for design optimization, and Sensitivity Analysis (SA). Weekly workflow scripts in the scripts directory demonstrate these methods in practice. Example datasets included in the data directory are used to support hands-on learning and experimentation.

For more detailed documentation on the modules in the surmod package, please view our documentation.

Information about the SEAM program is available to employees of Lawrence Livermore National Laboratory at https://seam.llnl.gov

Getting Started

1. Clone the repository

    git clone https://github.com/LLNL/SEAMsurrogates.git
    cd SEAMsurrogates

2. Create a virtual environment

    python3 -m venv .venv

3. Activate the virtual environment

    source .venv/bin/activate

4. Install dependencies

    pip install -r requirements.txt

5. Install the surmod package locally

    pip install -e .
