Summary

This repository aims to provide a package for multi-fidelity probabilistic machine learning. The package is developed by Jiaxiang Yi and Ji Cheng based on their learning curve on multi-fidelity probabilistic machine learning, and multi-fidelity Bayesian optimization, and multi-fidelity reliability analysis.

Overall, this mfpml package has two main goals, the first one is to provide basic code on implement typical methods in modeling, optimization, and reliability analysis field. Then, based on the basic code, we also provide some advanced methods based on our publications.

(1) Basic methods

Models

• Kriging model
• Multi-fidelity Kriging model

Optimizations

• Evolutionary algorithms
• Single fidelity Bayesian optimization
• Multi-fidelity Bayesian optimization

Reliability analysis

• Active learning reliability analysis
• Multi-fidelity reliability analysis

(2) Advanced methods

For the advanced methods, we will provide code based on our publications. please check out those papers:
