On Restricted Nonnegative Matrix Factorization
Dmitry Chistikov, Stefan Kiefer, Ines Marušić +2
Nonnegative matrix factorization (NMF) is the problem of decomposing a given nonnegative matrix into a product of a nonnegative matrix and a nonne…
Nonnegative Matrix Factorization Requires Irrationality
Dmitry Chistikov, Stefan Kiefer, Ines Marušić +2
Nonnegative matrix factorization (NMF) is the problem of decomposing a given nonnegative matrix into a product of a nonnegative matrix and a nonne…
Rational Bézier Curves Approximated by Bernstein-Jacobi Hybrid Polynomial Curves
Mao Shi
In this paper, we propose a linear method for approximation of rational Bézier curve with arbitrary degree polynomial curve. Based on weighted least-squares, the proble…
Efficient Quantile Computation in Markov Chains via Counting Problems for Parikh Images
Christoph Haase, Stefan Kiefer, Markus Lohrey
A cost Markov chain is a Markov chain whose transitions are labelled with non-negative integer costs. A fundamental problem on this model, with applications in the verification of…
