The computational complexity of inference from data is dominated by the solution of non-analytic numerical problems (large-scale linear algebra, optimization, integration, the solution of differential equations). But a converse of sorts is also true — numerical algorithms for these tasks are inference engines! They estimate intractable, latent quantities by collecting the observable result of tractable computations. Because they also decide adaptively which computations to perform, these methods can be interpreted as autonomous learning machines. This observation lies at the heart of the emerging topic of Probabilistic Numerical Computation, which applies the concepts of probabilistic (Bayesian) inference to the design of algorithms, assigning a notion of probabilistic uncertainty to the result even of deterministic computations. I will outline how this viewpoint is connected to that of classic numerical analysis, and show that thinking about computation as inference affords novel, practical answers to the challenges of large-scale, big data, inference.

Planetenbabys gesucht – wie Astronomen versuchen, Planeten bei der Geburt zu beobachten
- Date: Oct 9, 2018
- Time: 19:00 - 20:30
- Speaker: Prof. Dr. Til Birnstiel (LMU)
- Location: Muffatwerk
Wie die Welt um uns herum entstanden ist, gehört zu den ältesten Fragen der Menschheit. Zwar haben Astronomen inzwischen außerhalb unseres Sonnensystems viele weitere Planetensysteme entdeckt, dennoch bleibt die Entstehung von Planeten weiterhin rätselhaft. Um der Lösung dieses alten Rätsels etwas näher zu kommen, versuchen die Forscher die jüngsten Planeten zu beobachten – Planeten, die noch in der Scheibe aus Gas und Staub stecken, aus der sie entstanden sind. Das größte Radioteleskop der Welt, „ALMA“ in den nordchilenischen Anden, ermöglicht es, Spuren im Staub aufzuspüren, die als mögliche Hinweise auf solche Planetenbabys gelten. Was die Forscher bei dieser Suche entdeckten und wie sie den Dopplereffekt nutzen, um bislang unsichtbare Planeten sichtbar zu machen, erläutert Prof. Dr. Til Birnstiel von der Ludwig-Maximilans-Universität München.
