In the last few years, the interest in the analysis of human behavioral schemes has dramatically grown, in particular for the interpretation of the communication modalities called social signals. They represent well defined interaction patterns, possibly unconscious, characterizing different conversational situations and behaviors in general. In this paper, we illustrate an automatic system based...
Recently, we have proposed ant colony optimization (ACO) algorithm together with traveling salesman problem (TSP) approach to cluster proteins in protein interaction network (PIN). Our proposal described the general adaptation of ACO to perform the clustering tasks, including the optimal path finding in PIN. In this paper, we focus precisely on the process of finding an optimal path by ACO for the...
To facilitate interpretation and consider the relationships of internal interdependency between data values, a new form of high-order (multiple-valued) pattern known as Nested High-Order Pattern (NHOP) is presented. This pattern satisfies a consistent statistical criterion when the pattern is iteratively extracted. The general form of High-Order Pattern (HOP), that NHOP is a subtype, is a set of multiple...
