Symbolic Data Analysis

International Journal of Signs and Semiotic Systems, 2014
Standard data mining techniques no longer adequately represent the complexity of the world. So, a new paradigm is necessary. Symbolic Data Analysis is a new type of data analysis that allows us to represent the complexity of reality, maintaining the internal variation and structure developed by Diday (2003). This new paradigm is based on the concept of

Symbolic Objects and Symbolic Data Analysis

2005
Today’s technology allows storing vast quantities of information from different sources in nature. This information has missing values, nulls, internal variation, taxonomies, and rules. We need a new type of data that allow us to represent the complexity of reality, maintaining the internal variation and structure (Bock & Diday, 2000; Diday, 2002 ...

Principal component analysis of interval data: a symbolic data analysis approach

Computational Statistics, 2000
Statistical methods have been mainly developed for the analysis of single-valued variables. However, in real life there are many situations in which the use of these variables may cause severe loss of information. Dealing with quantitative variables, there are many cases in which a more complete information can be surely achieved by describing a set of

Data base for symbolic network analysis

IEE Proceedings G (Electronic Circuits and Systems), 1981
A data base for generating the symbolic transfer functions for a linear electronic circuit is formulated and an appropriate retrieval theorem derived. The size of the required data base is 0 (n2) independently of the number of simultaneously varying parameters, where n is the total number of component output terminals, and the cost of retrieval is 0 ...

Principles on Symbolic Data Analysis

2009
Today’s technology allows storing vast quantities of information from different sources in nature. This information has missing values, nulls, internal variation, taxonomies, and rules. We need a new type of data analysis that allows us represent the complexity of reality, maintaining the internal variation and structure (Diday, 2003). In Data Analysis
