Method for estimating critical exponents in percolation processes with low sampling
Nikolaos Bastas, Kosmas Kosmidis, Paraskevas Giazitzidis +1
In phase transition phenomena, the estimation of the critical point is crucial for the calculation of the various critical exponents and the determination of the universality class…
Parallel and Distributed Collaborative Filtering: A Survey
Efthalia Karydi, Konstantinos G. Margaritis
Collaborative filtering is amongst the most preferred techniques when implementing recommender systems. Recently, great interest has turned towards parallel and distributed impleme…
Mobile recommender systems: An overview of technologies and challenges
Nikolaos Polatidis, Christos K. Georgiadis
The use of mobile devices in combination with the rapid growth of the internet has generated an information overload problem. Recommender systems is a necessity to decide which of…
Factors Influencing the Quality of the User Experience in Ubiquitous Recommender Systems
Nikolaos Polatidis, Christos K. Georgiadis
The use of mobile devices and the rapid growth of the internet and networking infrastructure has brought the necessity of using Ubiquitous recommender systems. However in mobile de…
A Hybrid Parallel Implementation of the Aho-Corasick and Wu-Manber Algorithms Using NVIDIA CUDA and MPI Evaluated on a Biological Sequence Database
Charalampos S. Kouzinopoulos, John-Alexander M. Assael, Themistoklis K. Pyrgiotis +1
Multiple matching algorithms are used to locate the occurrences of patterns from a finite pattern set in a large input string. Aho-Corasick and Wu-Manber, two of the most well know…
Explosive Percolation: Unusual Transitions of a Simple Model
Nikolaos Bastas, Paraskevas Giazitzidis, Michael Maragakis +1
In this paper we review the recent advances on explosive percolation, a very sharp phase transition first observed by Achlioptas et al. (Science, 2009). There a simple model was pr…
