Algebra, matrices, and computers
[SNAP2019005EN] (Mathematisches Forschungsinstitut Oberwolfach, 20190503)What part does algebra play in representing the real world abstractly? How can algebra be used to solve hard mathematical problems with the aid of modern computing technology? We provide answers to these questions that ... 
1605  Algebraic Cobordism and Projective Homogeneous Varieties
[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 ...
