High-performance framework for uncertainty quantification, optimization and reinforcement learning.

Build Status Documentation Status Code Coverage

Korali is a high-performance framework for Bayesian UQ, optimization, and reinforcement learning. Korali’s multi-language interface allows the execution of any type of computational model, either sequential or distributed (MPI), C++ or Python, and even pre-compiled/legacy applications. Korali’s execution engine enables scalable sampling on large-scale HPC systems.

Korali provides a simple interface that allows users to easily describe statistical / deep learning problems and choose the algorithms to solve them. The framework can easily be extended to describe new problems or test new experimental algorithms on existing problems.
