ROBUSTNESS AGAINST READ COMMITTED FOR TRANSACTION TEMPLATES WITH FUNCTIONAL CONSTRAINTS Vrije Universiteit Brussel Hasselt University
The popular isolation level Multiversion Read Committed (RC) trades some of the strong guarantees of serializability for increased transaction throughput. Sometimes, transaction workloads can be safely executed under RC obtaining serializability at the lower cost of RC. Such workloads are said to be robust against RC. Previous work has yielded a tractable procedure for deciding robustness against RC for workloads generated by transaction ...
SoftVAD in iVector-based acoustic scene classification for robustness to foreground speech Ghent University
To increase the robustness of Acoustic Scene Clas-sification (ASC) during foreground speech presence, we recently proposed a noise-floor based iVector framework exploiting the statistical estimate of the background signal spectrum. Thereby, ASC accuracy was greatly improved when foreground speech was predominant, at the cost of poorer performance in scenarios with low foreground speech levels. A soft Voice Activity Detector (softVAD) is ...
Robustness Against Read Committed: A Free Transactional Lunch Hasselt University Vrije Universiteit Brussel
Transaction processing is a central part of most database applications. While serializability remains the gold standard for desirable transactional semantics, many database systems offer improved transaction throughput at the expense of introducing potential anomalies through the choice of a lower isolation level. Transactions are often not arbitrary but are constrained by a set of transaction programs defined at the application level (as is the ...
A study of the U.S. domestic air transportation network: temporal evolution of network topology and robustness from 2001 to 2016 Vrije Universiteit Brussel KU Leuven
The U.S. air transportation network (ATN) is critical to the mobility and the functioning of the United States. It is thus necessary to ensure that it is well-connected, efficient, robust, and secure. Despite extensive research on its topology, the temporal evolution of the network’s robustness remains largely unexplored. In the present paper, a methodology is proposed to identify long-term trends in the evolution of the network’s topology and ...
Adversarial robustness of probabilistic network embedding for link prediction Ghent University
In today's networked society, many real-world problems can be formalized as predicting links in networks, such as Facebook friendship suggestions, e-commerce recommendations, and the prediction of scientific collaborations in citation networks. Increasingly often, link prediction problem is tackled by means of network embedding methods, owing to their state-of-the-art performance. However, these methods lack transparency when compared to simpler ...
Robustness, sensitivity, and sampling variability of pareto-optimal selection system solutions to address the quality-diversity trade-off Ghent University
Continuous twin screw granulation : robustness of lactose/MCC-based formulations Ghent University
In recent years, significant progress has been made in the field of continuous twin screw granulation. However, only limited knowledge is currently available on the impact of active pharmaceutical ingredient (API) properties on granule quality and processability. In this study, the response behavior of four formulations containing APIs (5–10% drug load) with diverse characteristics was compared to the behavior of the corresponding placebo ...
