ABSTRACT Context-awareness is viewed as one of the most important aspects in the emerging pervasive computing paradigm. Mobile context-aware
applications are required to sense and react to changing environment conditions. Such applications, usually, need to recognize,
classify and predict context in order to act efficiently, beforehand, for the benefit of the user. In this paper, we propose
a mobility prediction model, which deals with context representation and location prediction of moving users. Machine Learning
(ML) techniques are used for trajectory classification. Spatial and temporal on-line clustering is adopted. We rely on Adaptive
Resonance Theory (ART) for location prediction. Location prediction is treated as a context classification problem. We introduce
a novel classifier that applies a Hausdorff-like distance over the extracted trajectories handling location prediction. Since
our approach is time-sensitive, the Hausdorff distance is considered more advantageous than a simple Euclidean norm. A learning
method is presented and evaluated. We compare ART with Offline kMeans and Online kMeans algorithms. Our findings are very promising for the use of the proposed model in mobile context aware applications.
