[OWR20165] (2016)  (31 Jan  06 Feb 2016)The aim of this workshop was to bring together researchers in the theory of projective homogeneous varieties with researchers working on cohomology theories of algebraic varieties, so that the latter can learn about the ... 
The algebraic combinatorial approach for lowrank matrix completion
[OWP201305] (Mathematisches Forschungsinstitut Oberwolfach, 20130314)We propose an algebraic combinatorial framework for the problem of completing partially observed lowrank matrices. We show that the intrinsic properties of the problem, including which entries can be reconstructed, and ... 
Algebraic geometric comparison of probability distributions
[OWP201130] (Mathematisches Forschungsinstitut Oberwolfach, 20110527)We propose a novel algebraic framework for treating probability distributions represented by their cumulants such as the mean and covariance matrix. As an example, we consider the unsupervised learning problem of finding ...

Algebraic Matroids with Graph Symmetry
[OWP201402] (Mathematisches Forschungsinstitut Oberwolfach, 2014)This paper studies the properties of two kinds of matroids: (a) algebraic matroids and (b) finite and infinite matroids whose ground set have some canonical symmetry, for example row and column symmetry and transposition ...

[OWR201720] (2017)  (16 Apr  22 Apr 2017)Algebraic Statistics is concerned with the interplay of techniques from commutative algebra, combinatorics, (real) algebraic geometry, and related fields with problems arising in statistics and data science. This workshop ... 
The Algebraic Statistics of an Oberwolfach Workshop
[SNAP2018001EN] (Mathematisches Forschungsinstitut Oberwolfach, 20180227)Algebraic Statistics builds on the idea that statistical models can be understood via polynomials. Many statistical models are parameterized by polynomials in the model parameters; others are described implicitly by ...
