Dimitrovski, T. (author), Bergman, T. (author), Zuraniewski, P. (author)The use of Machine Learning in many control and management processes is rising fast. This is especially true for the management of cloud native applications and for anomaly detection in cyber-security mechanisms. However, it has been shown that ML is an attack surface on its own, especially when the attack is performed by another ML system....conference paper 2023

Frommholz, D. (author), Kuijper, F. (author), Bulatov, D. (author), Cheung, D. (author)This paper discusses a rapid workflow for the automated generation of geospecific terrain databases for military simulation environments. Starting from photogrammetric data products of an oblique aerial camera, the process comprises deterministic terrain extraction from digital surface models and semantic building reconstruction from 3D point...conference paper 2022

Veugen, P.J.M. (author), Kamphorst, B (author), van de L'Isle, N. (author), van Egmond, M.B. (author)We show how multiple data-owning parties can collabora tively train several machine learning algorithms without jeopardizing the privacy of their sensitive data. In particular, we assume that every party knows specific features of an overlapping set of people. Using a secure implementation of an advanced hidden set intersection protocol and a...conference paper 2021

Erkin, Z. (author), Veugen, T. (author), Toft, T. (author), Lagendijk, R.L. (author)Clustering is a very important tool in data mining and is widely used in on-line services for medical, financial and social environments. The main goal in clustering is to create sets of similar objects in a data set. The data set to be used for clustering can be owned by a single entity, or in some cases, information from different databases is...article 2013

Moes, T.H. (author), Wijbenga, J.P. (author), Balsters, H. (author), Huitema, G.B. (author)This paper describes a method used in a real-life case of a legacy database migration. The difficulty of the case lies in the fact that the legacy application to be replaced has to remain fully available during the migration process while at the same time data from the old system is to be integrated within the new system. The target database...conference paper 2012

Lefter, I. (author), Rothkrantz, L.J.M. (author), Wiggers, P. (author), van Leeuwen, D.A. (author), TNO Defensie en Veiligheid (author)We explore possibilities for enhancing the generality, portability and robustness of emotion recognition systems by combining data-bases and by fusion of classifiers. In a first experiment, we investigate the performance of an emotion detection system tested on a certain database given that it is trained on speech from either the same database,...conference paper 2010

Yavuz, F. (author), van Tilburg, T. (author), David, P. (author), Spruijt, M. (author), Wildenborg, T. (author), TNO Bouw en Ondergrond (author)Carbon dioxide Capture and Storage (CCS) is a promising contribution to reduce further increase of atmospheric CO2 emissions from fossil fuels. The CCS concept anticipates that large amounts of CO2 are going to be stored in the subsurface for the long term. Since CCS is a rather new technology, uncertainties related with the future evolution of...article 2009

(author), TNO Kwaliteit van Leven (author)Objectives: Workers in many industries are exposed to endotoxins, which may cause adverse health effects. In exposure assessment, information about exposure variability is essential. However, variability in exposure has rarely been investigated for biological agents and more specifically for endotoxin. Therefore, variance components and...article 2008
