“Visualisation and exploration of high-dimensional data using
"force directed placement" method: application to the analysis of
genomic signature.” International Symposium on Applied
Models and Data Analysis, ASMDA 2005, 2005 may, pp. 230-237.
high-dimensional data is generally achieved by projection in a low
space (usually 2 to 3 dimensions). Visualization is designed to
understanding of data sets by preserving some "essential"
information. We have designed a non-linear multi-dimensional-scaling
relying on the force directed placement (FDP) paradigm to help
discover features of interest in data sets. A user-driven relaxation of
constraints built on the preservation of pairwise distances between
getting subjective representations of data that meet some specific
angle. In a
context of classification, we examine the impact of metric, sample
neighborhood preservation on the mapping of genomic signatures.
