Meta Answering for Machine Reading
(2019)arXivWe investigate a framework for machine reading, inspired by real world information-seeking problems, where a meta question answering system interacts with a black box environment. The environment encapsulates a competitive machine reader based on BERT, providing candidate answers to questions, and possibly some context. To validate the realism of our formulation, we ask humans to play the role of a meta-answerer. With just a small snippet ...Working Paper -
Strong structural controllability of signed networks
(2019)arXivIn this paper, we discuss the controllability of a family of linear time-invariant (LTI) networks defined on a signed graph. In this direction, we introduce the notion of positive and negative signed zero forcing sets for the controllability analysis of positive and negative eigenvalues of system matrices with the same sign pattern. A sufficient combinatorial condition that ensures the strong structural controllability of signed networks ...Working Paper -

Falschübersetzungen?
(2019)Die automatische Übersetzung natürlicher Sprachen hat in letzter Zeit zwar grosse Fortschritte gemacht, sie ist aber nach wie vor mangelhaft. So gibt es, wie dieser Bericht zeigt, Schwierigkeiten bei der Erkennung von Verbformen (2. Person Einzahl und Mehrzahl, Höflichkeitsform). Das wirkt sich vor allem bei der Übertragung in die Sprachen Französisch, Italienisch und Spanisch aus. Die Programme erkennen zudem offensichtliche Fehler im ...Working Paper -
Strong structural controllability under network perturbations
(2019)arXivThis paper investigates the robustness of strong structural controllability for linear time-invariant and linear time-varying directed networks with respect to structural perturbations, including edge deletions and additions. In this direction, we introduce a new construct referred to as a perfect graph associated with a network with a given set of control nodes. The tight upper bounds on the number of edges that can be added to, or removed ...Working Paper -
Quantitative Easing in the Euro area and SMEs Access to Finance: Who Benefits the Most?
(2019)After the global financial crisis and during the European sovereign debt crisis, bank lending to companies in the euro area slowed down dramatically, bringing the economy close to a credit crunch. It was only after the start of the European Central Bank (ECB) quantitative easing programme in early 2015 that bank lending improved sustainably. This study analyses the impact of the ECB's Public Sector Purchase Programme (PSPP) on the access ...Working Paper
