'''Overview: ''' This PhD thesis focuses on two strong points of the Data Mining Theme of the BFO team of ICube: relational data mining on the one hand, and cost-sensitive learning on the other hand. These two points are currently studied as part of the european project [http://www.reframe-d2k.org/index.php/Main_Page REFRAME], in collaboration with the [http://www.bris.ac.uk University of Bristol] and the [http://www.upv.es/index-en.html Polytechnic University of Valencia].

Relational data mining is a subfield of data mining where data is not represented according to the classic attribute-value model, in which every row of a single table would represent a training instance of a model with its properties, including the attribute to predict. Here, data is represented by several tables linked with foreign keys, which represent the different kinds of objects constituting the problem. A table, called the main table, contains the training instances (for instance, molecules) with the attribute to learn and other tables (for instance a table of the atoms constituting the molecules) contain the secondary objects linked to the main ones. We intend to take into account the properties of such secondary objects in the learning process on the main objects. A way to do so, in which we are more particularly interested, is the use of complex aggregates. They constitute a way to aggregate the secondary objects linked to one main object that meet a certain condition. More intuitively, the allow to summarize in one value the secondary table. Two examples of such an aggregate would be the number of carbon atoms in the molecule, or the average charge of the oxygen atoms of the molecule. However, the number of possibilities for the aggregate condition and the aggregate function make the exhaustive generation of all complex aggregates intractable. One of the goals of the PhD thesis is to propose a heuristic allowing to explore the complex aggregate space and to generate incrementally the ones that are relevant to address the given problem.

The other domain on which this PhD thesis focuses on is multi-class cost-sensitive learning. In this kind of problem, the attribute to learn can take many values, ''i.e.'' more than 2, contrary to the binary problems for which many learning algorithms are designed. Moreover, all the classification errors do not have the same cost, as expected in a medical domain, where diagnosing a disease for a sane patient will not have the same impact as not diagnosing the disease for a sick patient. In this framework, we are particularly interested in to binarization approaches, which consist in reducing a multi-class problem into several binary problems. More particularly, we consider the case where the binarization uses scorers, the scores being used to set decision thresholds between the two classes of the binary subproblems.

PhD Thesis

Title: Tactile quality control of products Formalizing the tactile control process of a product and proposing an automation approach

Overview: Perceived quality is a major factor of the choice and judgment of a product. Usually reduced to the appearance only, perceived quality refers to different senses, including touch, which is the topic of the proposed work. Generally described by subjective criteria, these data are hardly usable by design, industrialization and quality offices. These services would very much benefit from a formalized expertise process capable of converting the data from these senses into objective data. During this project, robust methodologies will be proposed, in order to develop relevant and repeatable measuring means of the tactile perceived quality of a product.
