ELLIS Talk: Geometric Gaussian Processes

Date: Wednesday, June 7, 2023 16:00 - 17:00
Speaker: Viacheslav Borovitskiy (ETH Z├╝rich)
Location: Heinzel Seminar Room / Office Bldg West (I21.EG.101)
Series: ELLIS talk
Host: Christoph Lampert

Gaussian processes (GPs) are often considered to be the gold standard in settings where well-calibrated predictive uncertainty is of utter importance, such as decision making.

It is important for applications to have a class of general purpose GPs. Traditionally, these are the stationary processes, e.g. RBF or Matrn GPs, at least for the usual vectorial inputs. For non-vectorial inputs, however, there is often no such class. This state of affairs hinders the use of GPs in a number of application areas ranging from robotics to drug design.

In this talk, I will consider GPs taking inputs on a manifold, on a node set of a graph, or in a discrete space of graphs. I will discuss a framework for defining the appropriate general purpose GPs, as well as the analytic and numerical techniques that make them tractable.
