Dr. Tomasz Szemberg
Linear systems with assigned base loci
* Wednesday 23 January 2019,   14:00,   M2 (M233)
I will report on special linear systems on complex projective spaces. Even though the topic is classical and studied for more than 100 years, many important questions are not answered in a satisfactory way.
Algebra Seminar

Dr. Justyna Szpond
Fermat-type configurations in projective spaces
* Wednesday 23 January 2019,   15:00,   M2 (M233)
A Fermat arrangement of lines in the complex projective plane is given by linear factors of the polynomial $(x^n-y^n)(y^n-z^n)(z^n-x^n)$ for some $n\geq 3$. Singular points of these arrangements have appeared recently in commutative algebra, more precisely in the containment problem between symbolic and ordinary powers of homogeneous polynomials and in algebraic geometry in the theory of linear systems and unexpected hypersurfaces. I will explain these two appearances and present considerable generalizations which led to substantial, new results in both fields.

Jaakko Lehtinen
Simulation + machine learning = interpretable, less data hungry AI?
Tuesday 29 January 2019,   15:00,   A2
How do we make computers perceive the everyday world and deeply understand it just by looking at it? How do we build virtual agents and real robots that build on this perception and are able to move and interact with the world, including us humans, in a natural manner? In this talk, I’ll talk about the currently accelerating congruence of physically-based simulation and machine learning in solving very hard problems in artificial intelligence. I’ll argue that the classic approach of “merely” learning from human-labeled examples is doomed – there is simply no way for us to cover all the variability in the real world with annotated examples – and that making use of interpretable models (simulators!) in the learning process is the way forward. I’ll give examples of my own work, as well as that of my close colleagues and collaborators, and other highlights from around the world.
