Network on Gaussian Processes

OUR MISSION

In essence, the concept of “Gaussian Processes” (GP) exists for many years, but during the last few years they pop up in different disciplines, often presented in a new toolkit.


In December 2019 we launched an interdisciplinary interest group around the possibilities and the challenges of GP. The objective was (and still is) the organic expansion of a platform for discussions and sharing of ideas on theoretical contributions and practical applications, creating a fertile soil for future cooperation and project proposals.


You should care about this topic as soon as you get involved in topics like probabilistic numerics, interpolation and optimization in uncertain environments, explainable machine learning, design of sample measurements and pseudo-inputs, etc...
