Predicting Early Dropouts of an Active and Healthy Ageing App
Vasileios Perifanis, Ioanna Michailidi, Giorgos Stamatelatos +2
In this work, we present a machine learning approach for predicting early dropouts of an active and healthy ageing app. The presented algorithms have been submitted to the IFMBE Sc…
FedPOIRec: Privacy Preserving Federated POI Recommendation with Social Influence
Vasileios Perifanis, George Drosatos, Giorgos Stamatelatos +1
With the growing number of Location-Based Social Networks, privacy preserving location prediction has become a primary task for helping users discover new points-of-interest (POIs)…
An Exact, Linear Time Barabási-Albert Algorithm
Giorgos Stamatelatos, Pavlos S. Efraimidis
This paper presents the development of a new class of algorithms that accurately implement the preferential attachment mechanism of the Barabási-Albert (BA) model to generate scale…
Lexicographic Enumeration of Set Partitions
Giorgos Stamatelatos, Pavlos S. Efraimidis
In this report, we summarize the set partition enumeration problems and thoroughly explain the algorithms used to solve them. These algorithms iterate through the partitions in lex…
About Weighted Random Sampling in Preferential Attachment Models
Giorgos Stamatelatos, Pavlos S. Efraimidis
The Barabási-Albert model is a popular scheme for creating scale-free graphs but has been previously shown to have ambiguities in its definition. In this paper we discuss a new amb…
