Article
Open AccessAir transport is one of the key infrastructures of today’s global economy. Connections between airports define airport networks, where nodes are cities served by airports, connected by edges if there is at least one direct ... -
Deep Learning For Sequential Pattern Recognition
(Universitat Politècnica de Catalunya / Technische Universität München, 2013-12-18)
Master thesis
Open Access
Covenantee: Technische Universität MünchenIn recent years, deep learning has opened a new research line in pattern recognition tasks. It has been hypothesized that this kind of learning would capture more abstract patterns concealed in data. It is motivated by the ... -
Diffusion capacity of single and interconnected networks
(2023-04-18)
Article
