UM-Bridge

UM-Bridge (the UQ and Model Bridge) provides a unified interface for numerical models that is accessible from virtually any programming language or framework. It is primarily intended for coupling advanced models (e.g. simulations of complex physical processes) to advanced statistical or optimization methods.

In many statistical / uncertainty quantification or optimization methods, the model only appears as a function mapping vectors onto vectors with some of the following:

The key idea of UM-Bridge is to now provide this mathematical “interface” as an abstract interface in software as well. By using HTTP behind the scenes, a high degree of flexibility is achieved, allowing for:

Part of this project is a library of pre-defined models and benchmarks.
