Abstract:

Avec le développement du cloud computing, de nouveaux services voient le jour et il devient primordial que les utilisateurs aient les outils nécessaires pour choisir parmi ses services. La théorie des ensembles approximatifs représente un bon outil de traitement de données incertaines. Elle peut exploiter les connaissances cachées ou appliquer des règles sur des ensembles de données. Le but principal de cette thèse est d'utiliser la théorie des ensembles approximatifs pour aider les utilisateurs de cloud computing à prendre des décisions.

Abstract:

Each image in a Content Based Image Retrieval (CBIR) system is represented by its features such as colour, texture and shape. These three groups of features are stored in the feature vector. Therefore, each image managed by the CBIR system is associated with one or more feature vectors. As a result, the storage space required for feature vectors is proportional to the amount of images in the database. In addition, when comparing the similarities among images, the CBIR needs to compare these feature vectors. Nonetheless, researchers are still facing problems when working with a huge image datab

Abstract:

Fuzzy set theory was presented for the first time by Professor Lotfi A. Zadeh from Berkeley University in 1965. In conventional binary logic a statement can be true or false, and there is no place for even a little uncertainty in this judgment. An element either belongs to a set or does not. We call these kinds of sets crisp sets. In practice we often experience those real situations that are represented by crisp sets as impossible to describe accurately. A two-valued logic assumes that precise symbols must be employed, and it is therefore not applicable to the real existence. If the informati

A dynamic database is a common type in many business databases, and the data deletion operations that are also frequently used in database management activities. Unfortunately, most existing data-mining algorithms assume that the database is static, and updating a database requires to re-compute all the patterns by scanning the updated database after deleting data for data mining and rule extraction.

It is capable of discovering important facts hidden in that data. However, previous literature indicated these rough set approaches cannot guarantee that the classification of a decision table is credible. Therefore, Tseng (2006) proposed the REA (Rule-Extraction Algorithm) to solve the problem. But the desired reducts are not necessarily unique since several reducts could include the same value of SI. Thus, Tseng (2008) proposed AREA (Alternative Rule Extract

While the risk of loss and diversion, unsafe ammunition stocks occurs, the scales of the risks they pose are significant.
