Geometry of Data Sets

Abstract

  • Entity-to-variable data table can be represented geometrically in three different settings of which one (row-points) pertains to conventional clustering, another (column-vectors), to conceptual clustering, and the third one (matrix space), to approximation clustering.

  • Two principles for standardizing the conditional data tables are suggested as related to the data scatter.

  • Standardizing the aggregable data is suggested based on the flow index concept introduced.

  • Graph-theoretic concepts related to clustering are considered.

  • Low-rank approximation of data, including the popular Principal component and Correspondence analysis techniques, are discussed and extended into a general Sequential fitting procedure, SEFIT, which will be employed for approximation clustering.
