On Information Fusion in the Life-Sciences

In the present text, we shall discuss soft computing as concerned with the fusion of qualitative percepts and quantitative measurements. Whereas the former is obtained from observation, we shall assume that the latter is collected through measurements. Bo

PREFACE

This volume contains revised papers read originally at the 5th workshop on "Data Fusion and Perceptions", Centre International des Sciences Mecaniques (CISM), Udine, Italy, October 5-7, 2000. As usual this international workshop was peifectly conveyed by the International School for the Synthesis of Expert Knowledge (ISSEK) and held in the impressive Palazzo del Torso of the Centre International des Sciences Mecaniques (CISM), Udine. G. Della Riccia (University of Udine), R. Kruse (University of Magdeburg), and H.-J. Lenz (Free University Berlin) jointly recruited leading researchers from various fields in Europe, and planned the final scientific program. The (innocent) reader may ask why the topic of this conference was chosen as above. First, Data Fusion and Perceptions are mainstream topics of current research. Second, their semantics and pragmatics are continuously extended, and more and more fields of applications are discovered despite of the curse of dimension and size of databases. This became possible due to the progress of computing power and storage devices. In its proper sense Data Fusion is understood as a rather new methodology, where heterogeneous data are merged and a measure of quality is computed. This measure differs from complexity measures used in database joins and data access plans. For example, hit rates equal to one minus error rates may be approp
