Digestive Database Evidential Clustering Based on Possibility Theory
نویسندگان
چکیده
A new method that aims to automatically classify a set of objects in spite of the imperfection and the uncertainty of their heterogeneously-assigned data is proposed in this paper. This method is based essentially on possibility theory to estimate the similarity among the objects, and on belief theory and multidimensional scaling methods to construct the compatible evidential class partition. This method is applied to a medical database and robust results have been obtained without knowing the key attributes of the concerned pathologies and without taking into account any a priori medical knowledge. Key-Words: Possibility Theory, Evidence Theory, Similarity, Clustering, Partition, Multi-Dimensional Scaling.

CEVCLUS: Constrained evidential clustering of proximity data
We present an improved relational clustering method integrating prior information. This new algorithm, entitled CEVCLUS, is based on two concepts: evidential clustering and constraint-based clustering. Evidential clustering uses the DempsterShafer theory to assign a mass function to each object. It provides a credal partition, which subsumes the notions of crisp, fuzzy and possibilistic partiti...
متن کاملRECM: Relational evidential c-means algorithm
A new clustering algorithm for proximity data, called RECM (Relational evidential c-means) is presented. This algorithm generates a credal partition, a new clustering structure based on the theory of belief functions, which extends the existing concepts of hard, fuzzy and possibilistic partitions. Two algorithms, EVCLUS (Evidential Clustering) and ECM (Evidential c-Means) were previously availa...

متن کاملPAOLA PIETRANDREA (Rome) KATERINA STATHI (Berlin) What counts as an evidential unit? The case of evidential complex constructions in Italian and Modern Greek
The evidential meaning traditionally attributed to modal auxiliaries is conveyed in Italian and Greek by complex constructions clustering both modal and aspectual features. The evidential reading of Italian and Greek modal auxiliaries, indeed, is only licenced when the modals take as complements stative, progressive, habitual or resultative subordinates. A feature of aspectual incompleteness of...
متن کاملMedian evidential c-means algorithm and its application to community detection
Median clustering is of great value for partitioning relational data. In this paper, a new prototype-based clustering method, called Median Evidential C-Means (MECM), which is an extension of median c-means and median fuzzy c-means on the theoretical framework of belief functions is proposed. The median variant relaxes the restriction of a metric space embedding for the objects but constrains t...
