For large customers, Electricité de France the French national electric power company stores every 10’ the amount of electric power they consume. For each customer, these measures lead to curves called electric load curves. Clustering of electric load curves is a key problem for understanding the behavior of these customers. Several methods have been used but Kohonen maps give a very nice solut...

The goal of the paper is to present a speech nonfluency detection method based on linear prediction coefficients obtained by using the covariance method. The application “Dabar” was created for research. It implements three different methods of LP with the ability to send coefficients computed by them into the input of Kohonen networks. Neural networks were used to classify utterances in catego...

The safety of gas cylinders in domestic applications is of utmost importance. A crucial stage in the appraisal of the risk for failures and possible faults is occurring during the filling process. In Cyprus, this task is currently done by specialized workers who monitor the cylinders during filling. In order to explore the possibility for an automated risk appraisal and consequent screening, a ...

Artificial Neural Network (ANN) is the primary automated AI system preferred for medical applications. Even though ANN possesses multiple advantages, the convergence of the ANN is not always guaranteed for the practical applications. This often results in the local minima problem and ultimately yields inaccurate results. This convergence problem is common among ANNs and especially in Kohonen ne...

Previous work has investigated the use of data clustering of regional species assemblages to estimate the relative risk of establishment of insect crop pest species. This paper describes the use of these techniques to estimate the risk posed by bacterial crop plant diseases. Two widely-used clustering algorithms, the Kohonen Self-Organising Map and the k-means clustering algorithm, were investi...
