Project Milestone Checklist

Urgent Functionality

• Integrate update() function into both homGP and hetGP.
• Create multiHomGP and multiHetGP for multidimensional simulation models (similar to pcHomGP and pcHetGP).
• Extend update() function to both multiHomGP and multiHetGP.
• Integrate the above functionalities into the sequential procedures and acquisition functions proposed for stochastic models.
• Add new Example 4 and Example 5 folders to demonstrate stochastic model use cases.
• Merge this version into the develop branch and prepare for push to main.

Functionality

• Extend multiHomGP using dimensionality reduction (e.g., PCA).
• Refactor surrogate.py to remove theta as an input (i.e., use x as the only input) and update the emulators accordingly.
• Investigate whether hetgpy.IMSE can be used.
• Investigate whether hetgpy.covariance_functions can be used.
• The current batch sequential approach uses joblib synchronously. Explore whether it can be extended for asynchronous runs.
• Design a unified framework for defining acquisition functions; review how other Python packages implement this.
• Design a unified framework for sequential data collection; review how other Python packages implement this.
