Dear all,

this is a reminder for the next UnRAVeL survey lecture that takes place 
this *Thursday, May 20 at 4:30pm*.*Martin Grohe *will talk about *The 
Logic of Graph Neural Networks*. Following the talk, UnRAVeL PhD student 
*Tim Seppelt* will give an informal summary of their doctoral studies 
within UnRAVeL.

> *Abstract*
> Graph neural networks (GNNs) are a deep learning architecture for 
> graph structured data that has developed into a method of choice for 
> many graph learning problems in recent years. It is therefore 
> important that we understand their power. One aspect of this is the 
> expressiveness: which functions on graphs can be expressed by a GNN 
> model? Surprisingly, this question has a precise answer in terms of 
> logic and a combinatorial algorithm known as the Weisfeiler–Leman 
> algorithm.
>
> In my lecture, I will introduce the basic GNN architecture and also 
> some extensions, and I will explain the logical characterisations of 
> their expressiveness.

Dear all,

part of the programme of the research training group UnRAVeL is a series 
of introductory lectures on the topics of „randomness“ and „uncertainty“ 
in UnRAVeL’s research thrusts algorithms and complexity, verification, 
logic and languages, and their application scenarios. Each lecture is 
delivered by one of the researchers involved in UnRAVeL. The main aim is 
to provide doctoral researchers as well as master students a broad 
overview of the subjects of UnRAVeL.

This year, 12 UnRAVeL professors will answer the following questions, 
based on one of their recent scientific results:

  * How did you get to this result?
  * How did you come up with certain key ideas?
  * How did you cope with obstacles on the way? Which ideas you had did
    not work out?

Following these talks, PhD students will give an informal summary of 
their doctoral studies within UnRAVeL.

All interested doctoral researchers and master students are invited to 
attend the UnRAVeL lecture series 2021 and engage in discussions with 
researchers and doctoral students.

Details information can be found on 
https://www.unravel.rwth-aachen.de/cms/UnRAVeL/Studium/~pzix/Ringvorlesung-Veranstaltung/?lidx=1

All events take place on *Thursdays from 16:30 to 18:00 on Zoom*
