Auditing and Achieving Intersectional Fairness in Classification Problems
Giulio Morina, Viktoriia Oliinyk, Julian Waton +2
Machine learning algorithms are extensively used to make increasingly more consequential decisions about people, so achieving optimal predictive performance can no longer be the on…
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…
Minimisation of Multiplicity Tree Automata
Stefan Kiefer, Ines Marusic, James Worrell
We consider the problem of minimising the number of states in a multiplicity tree automaton over the field of rational numbers. We give a minimisation algorithm that runs in polyno…
Complexity of Equivalence and Learning for Multiplicity Tree Automata
Ines Marusic, James Worrell
We consider the complexity of equivalence and learning for multiplicity tree automata, i.e., weighted tree automata over a field. We first show that the equivalence problem is logs…
