Data Probes, Vertical Trajectories and Classification: A Tentative StudyIn this paper we introduce a method of classification based on data probes. Data points are considered as point masses in space and a probe is simply a particle that is launched

We are interested in the problem of the mathematical modelling and simulation of groups of small enterprises. This is where a network of small enterprises is established in order to achieve a global objective. Each enterprise contributes to the netwo

Air pollution is one of the primary environmental concerns in France due to the public health question. People wish to be informed of the air pollution level in real time or to be warned in advance of a peak of pollution. The goal of this study is to

In this paper we study the local approximation problem, i.e. given a certain type of control system described by a set of differential equations can we construct an artificial neural network of Hopfield type that is a local approximation (in a well d

Recurrent neural network state-space trajectories can be considered as local one-parameter transformation groups. If such a group transforms the solution of a certain equation to another solution of the same equation then the group is referred to as

In this paper we study continuous time nonlinear artificial neural networks of Hopfield type using geometrical and topological methods. A particularly useful geometrical concept, the Lie algebra of analytical vector fields, is employed. Under certain

The Levenstein or edit distance was developed as a metric for calculating distances between character strings.We are looking at weighting the different edit operations (insertion, deletion, substitution) to obtain different types of classifications o

In this paper we look at a dynamic method for analysing data, called a data probe. The probe flies through the data space and is affected by the proximity and number of data points. The trajectory followed by the probe provides information about how

In this paper we present a method that leads to the improvement of a subtractive clustering model by modifying the centres. In order to keep within certain bounds, a centre is modified by rotating it.
