The multi-source information holds a great importance in processing complex and imprecise data. Unfortunately, it requires an adequate formalism capable to modelize and to fuse several information. The evidence theory distinguishes from all formalism by its capacity to modelize and treat imprecise and imperfect data. In this context, the high resolution images represent a huge amount of data and needs multi-source information to perform pattern recognition. In this paper, we present an adaption of the distance operator introduced by Denoeux for estimating belief functions. This proposed approach will be used to classify forest image remote sensing by identifying the tree crown classes.

Supervised classification is a spot/task of data mining which consists in building a classifier from a set of examples labeled by their class (learning step) and then predicting the class of new examples with a classifier (classification step). In supervised classification, several approaches were proposed such as: Induction of Decision Trees, and Formal Concept Analysis. The learning of formal concepts is based, generally, on the mathematical structure of Galois lattice (or concept lattice). The complexity of generation of Galois lattice, limits the application fields of these systems. In this paper, we present several methods of supervised classification based on Formal Concept Analysis. We present methods based on concept lattice or sub lattice. We also present the boosting of classifiers, an emerging technique of classification. Finally, we propose the boosting of formal concepts: a new adaptive approach to build only a part of the lattice including the best concepts. These concepts are used as classification rules. Experimental results are given to prove the interest of the proposed method. © 2009 Springer Berlin Heidelberg.

An evaluation of the Alabama Smile Keeper Dental Health Education Program was necessary to determine if educating teachers to teach preventive dentistry improved the oral hygiene and knowledge of dental health of elementary schoolchildren. Four hundred seventy-five students at the Maxwell Air Force Base elementary school in grades 1 through 6 were tested using a series of written examinations and scores from a plaque index (Greene's OHI-S Index) before and after the education program. Levels of plaque were significantly reduced immediately after instruction and retention test scores were significantly lower four months later than preinstruction test scores. Written examinations proved that knowledge increased immediately after instruction and retention test scores were significantly better than preinstruction test scores.

Some experiments in the numerical analysis of archaeological data

引用

Biometrika 1966年第3-4期53卷 311-324页

作者： HODSON, F. R. SNEATH, P. H. A. DORAN, J. E. London University Institute of Archaeology Leicester University M.R.C. Microbial Systematics Research Unit Edinburgh University Experimental Programming Unit

The value for archaeology of some available methods of numerical classification was investigated. Brooches from an Iron Age site in Switzerland (Münsingen) were chosen for analysis for two reasons: they show variation over a typically wide range of attributes, and their archaeological context, in rich associations in a horizontally stratified cemetery, provides independent evidence to check the significance of any proposed classifications. A further control on results was provided by an ‘intuitive’ classification of the brooches by professional archaeologists. The brooches were described numerically by quantitative and qualitative characters, and a similarity coefficient was computed between each pair. These coefficients were then submitted to two forms of cluster analysis (single- and average-link) and to a multi-dimensional scaling procedure. The average-link, but not the single-link, cluster analysis and the multi-dimemional scaling procedure were found to produce classifications of demonstrable archaeological significance.
