Enhancing the Performance of Decision Tree Using NSUM Technique for Diabetes Patients

Abstract: Diabetes is a common disease among children to adult in this era. To prevent the diseases is very important because it saves the human lives. Data mining technique helps to solve the problem of predicting diabetes. It has steps of processes to predict the illness. Feature selection is an important phase in data mining process. In feature selection when dimension of the data increases, the quantity of data required to deliver a dependable analysis raises exponentially. Numerous different feature selection and feature extraction techniques are present, and they are widely used filter-based feature selection method is proposed which takes advantage of the wrapper, Embedded, hybrid methods by evaluating with a lower cost and improves the performance of a classification algorithm like a decision tree, support vector machine, logistic regression and so on. To predict whether the patient has diabetes or not, we introduce a novel filter method ranking technique called Novel Symmetrical Uncertainty Measure (NSUM). NSUM technique experimentally shows that compared to the other algorithms in filter method, wrapper method, embedded method and hybrid method it proves more efficient in terms of Performance, Accuracy, Less computational complexity. The existing technique of symmetric uncertainty measure shows less computational power and high performance, but it lacks in accuracy. The aim of the NSUM method is to overcome the drawback of the filter method, i.e., less accuracy compared to other methods. NSUM technique results show high performance, improved accuracy, and less computational complexity. NSUM method runs in 0.03 s with 89.12% as accuracy by using Weka tool.

Caractérisation des éléments de solutions en recherche d'information : conception d'un modèle dynamique dans un contexte décisionnel

Abstract: L'activite de veille, au sein du processus d'Intelligence Economique, est principalement une activite de resolution de probleme de recherche d'information. Cette activite de veille est realisee par le veilleur qui doit localiser, surveiller, valider et mettre en valeur l'information strategique, en collaboration avec le decideur qui doit formuler des objectifs aussi precis que possible pour la prise de decision. Afin d'optimiser le partage des connaissances entre le decideur et le veilleur nous avons developpe un modele pour la description de probleme de recherche d'information. Ce modele peut aider a augmenter la precision de la representation des differents parametres du probleme et permettre une plus grande performance de resolution et la reutilisation des elements de solution.

Cyberspace security: How to develop a security strategy

Abstract: Despite all visible dividers, the Internet is getting us closer and closer, but with a great price. Our security is the price. The international community is fully aware of the urgent need to secure the cyberspace as you see the multiplication of security standards and national schemes interpreting them beyond borders: ISO 15408, ISO 17799, and ISO 27001. Even though some countries, including the Security Big Six (SB6), are equipped with their security books and may feel relatively safe; this remains a wrong sense of security as long as they share their networks with entities of less security. The standards impose security best practices and system specifications for the development of information security management systems. Partners beyond borders have to be secure as this is only possible if all entities connected to the partnership remain secure. Unfortunately, there is no way to verify the continuous security of partners without periodic security auditing and certification, and members who do not comply should be barred from the partnership. This concept also applies to the cyber space or the electronic society. In order to clean our society from cyber crimes and cyber terrorism we need to impose strict security policies and enforce them in a cooperative manner. The paper discusses a country's effort in the development of a national security strategy given its security economic intelligence position, its security readiness, and its adverse exposure.

Modelisation des acteurs, des ressources documentaires : application a un entrepot universitaire

Abstract: Nous travaillons a la conception d'un entrepot de donnees de ressources documentaires dans un cadre pedagogique integrant la modelisation de l'utilisateur. La description de ressources, en vue de leur reutilisation dans des parcours de formation, evoquent les difficultes rencontrees et formulent des propositions pour combler des manques dans les normes existantes et rendre plus operationnels certains descriptifs. La modelisation des acteurs d'une part et des types de documents d'autre part, permettent d'elaborer des correlations afin d'ameliorer les reponses. La mise en relation des acteurs et des documents est possible par les meta-donnees de l'entrepot de donnees et la meta-modelisation de l'entrepot de donnees. Nous elaborons egalement les meta-donnees propres a l'entrepot de donnees qui definissent les meta-donnees structurelles et d'accessibilite propres au systeme de pilotage. Afin de proceder au mieux au developpement de notre contribution au systeme d'information strategique, la meta-modelisation de l'entrepot de donnees permet d'elaborer un schema directeur pour la construction de l'entrepot de donnees.
