DALE: Differential Accumulated Local Effects for efficient and accurate global explanations
Vasilis Gkolemis, Theodore Dalamagas, Christos Diou
Accumulated Local Effect (ALE) is a method for accurately estimating feature effects, overcoming fundamental failure modes of previously-existed methods, such as Partial Dependence…
Atrapos: Real-time Evaluation of Metapath Query Workloads
Serafeim Chatzopoulos, Thanasis Vergoulis, Dimitrios Skoutas +3
Heterogeneous information networks (HINs) represent different types of entities and relationships between them. Exploring, analysing, and extracting knowledge from such networks re…
Modeling of crisis periods in stock markets
Apostolos Chalkis, Emmanouil Christoforou, Theodore Dalamagkas +1
We exploit a recent computational framework to model and detect financial crises in stock markets, as well as shock events in cryptocurrency markets, which are characterized by a s…
SCHeMa: Scheduling Scientific Containers on a Cluster of Heterogeneous Machines
Thanasis Vergoulis, Konstantinos Zagganas, Loukas Kavouras +3
In the era of data-driven science, conducting computational experiments that involve analysing large datasets using heterogeneous computational clusters, is part of the everyday ro…
Simplifying Impact Prediction for Scientific Articles
Thanasis Vergoulis, Ilias Kanellos, Giorgos Giannopoulos +1
Estimating the expected impact of an article is valuable for various applications (e.g., article/cooperator recommendation). Most existing approaches attempt to predict the exact n…
Modeling asset allocation strategies and a new portfolio performance score
Apostolos Chalkis, Emmanouil Christoforou, Ioannis Z. Emiris +1
We discuss and extend a powerful, geometric framework to represent the set of portfolios, which identifies the space of asset allocations with the points lying in a convex polytope…
Ranking Papers by their Short-Term Scientific Impact
Ilias Kanellos, Thanasis Vergoulis, Dimitris Sacharidis +2
The constantly increasing rate at which scientific papers are published makes it difficult for researchers to identify papers that currently impact the research field of their inte…
Publishing Life Science Data as Linked Open Data: the Case Study of miRBase
Theodore Dalamagas, Nikos Bikakis, George Papastefanatos +2
This paper presents our Linked Open Data (LOD) infrastructures for genomic and experimental data related to microRNA biomolecules. Legacy data from two well-known microRNA database…
Diachronic Linked Data: Towards Long-Term Preservation of Structured Interrelated Information
Yannis Stavrakas, George Papastefanatos, Theodore Dalamagas +1
The Linked Data Paradigm is one of the most promising technologies for publishing, sharing, and connecting data on the Web, and offers a new way for data integration and interopera…
FreePub: Collecting and Organizing Scientific Material Using Mindmaps
Theodore Dalamagas, Tryfon Farmakakis, Manolis Maragkakis +1
This paper presents a creativity support tool, called FreePub, to collect and organize scientific material using mindmaps. Mindmaps are visual, graph-based represenations of concep…
