Goal-Driven Approach to Model Interaction between Viewpoints of a Multi-View KDD process

International audienceA data mining project is usually held by several actors (domain experts, data analysts, KDD experts ...), each with a different viewpoint. In this paper we propose to enhance coordination and knowledge sharing between actors of a multiview KDD analysis through a goal driven modeling of interactions between viewpoints. After a brief review of our approach of viewpoint in KDD, we will first develop a Goal Model that allows identification and representation of business objectives during the business understanding step of KDD process. Then, based on this goal model, we define a set of relations between viewpoints of a multi-view analysis; namely equivalence, inclusion, conflict and requirement

The rate of occurrence of failures for semi-Markov processes and estimation

This paper investigates the rate of occurrence of failures (ROCOF) of finite state semi-Markov systems. Firstly, a formula for evaluating the ROCOF for semi-Markov systems is derived. As a consequence of this result, we derive the ROCOF of Markov systems as well as the ROCOF of the alternating renewal processes and we give their asymptotic values. From the semi-Markov ROCOF formula, we propose a statistical estimator of this function. Finally, the uniform strong consistency and the asymptotic normality of this estimator are obtained.Rate of occurrence of failures Semi-Markov process Non-parametric estimator Asymptotic properties

The expected cumulative operational time for finite semi-Markov systems and estimation

In this paper we, firstly, present a recursive formula of the empirical estimator of the semi-Markov kernel. Then a non-parametric estimator of the expected cumulative operational time for semi-Markov systems is proposed. The asymptotic properties of this estimator, as the uniform strongly consistency and normality are given. As an illustration example, we give a numerical application

A Review of the integrated WEF nexus modeling platform in the NENA region: Morocco case study

Nowadays, the world is recognizing the water-food-energy (WEF) as a conceptual framework that aims to the implementation of the Sustainable Development Goals (SDGs). The WEF Nexus is being developed to support the integrity of national and more importantly local projects in the cross-sectoral partnerships and coordination to enhance the sustainable development outcomes from the different projects as well as avoiding the trade-offs. Most importantly, building a great synergy between the sectors is challenged by sectorial boundaries such as policy decisions, scaling investments, and cross-sectorial consequences, which leads to anticipation biases when it comes to social, economic, and environmental costs. This paper aims to review the latest integrated WEF Nexus modeling platform that has been developed in the NENA region during the project "Implementing the 2030 Agenda for Water Efficiency/Productivity and Water Sustainability in NENA Countries" (WEPS-NENA), led by the Food and Agriculture Organization of the United Nations (FAO) and supported by the Swedish International Development Cooperation Agency
