Clustering 1: monothetic vs. polythetic
Full lecture: http://bit.ly/K-means The aim of clustering is to partition a population into sub-groups (clusters). Clusters can be monothetic (where all cluster members share some common property) or polythetic (where all cluster members are similar to each other in some sense).

Clustering 2: soft vs. hard clustering
Full lecture: http://bit.ly/K-means A hard clustering means we have non-overlapping clusters, where each instance belongs to one and only one cluster. In a soft clustering method, a single individual can belong to multiple clusters, often with a confidence (belief) associated with each cl

This is Why Minimalism is a Thing
In this video I talk about why minimalism is a thing people follow in today's society. There is a reason, and it's a good one.

Rahim Moosa (Waterloo) / 28.03.2018 D-varieties and the Dixmier-Moeglin Equivalence About four years ago, a new application of the model theory of differentially closed fields arose. The target was the Dixmier-Moeglin equivalence problem (DME) in noncommutative affine algebras, as well a

Katrin Tent (Münster) / 30.03.2018 Ampleness in strongly minimal structures The notion of ampleness captures essential properties of projective spaces over fields. It is natural to ask whether any sufficiently ample strongly minimal set arises from an algebraically closed field. In this

Meng Chen: On the geography of 3 folds of general type IV (incomplete)
In this series of lectures, I will briefly introduce some results concerning the geometry inspired by the pluricanonical system |mK| of threefolds of general type. I will talk about the general method to estimate the lower bound of the canonical volume K^3 and the proof of a 3-dimensional

Producing Minimal Submanifolds via Gauge Theory
Daniel Stern (U Chicago) Abstract: The self-dual U(1)-Yang-Mills-Higgs functionals are a natural family of energies associated to sections and metric connections of Hermitian line bundles, whose critical points (particularly in the 2-dimensional and Kaehler settings) are objects of long-st
