Vecchia-Inducing-Points Full-Scale Approximations for Gaussian Processes
Researchers have developed a new approximation method called Vecchia-Inducing-Points Full-Scale (VIF) to improve the scalability of Gaussian processes. This approach combines global inducing points with local Vecchia approximations, offering enhanced accuracy and stability, particularly for large datasets. The VIF method is implemented in the open-source GPBoost library, providing efficient tools for machine learning and statistical analysis. AI
