Multivariate Data Analysis: Theory, Applications and Interpretation Issues

Dear Colleagues,

Data mining covers all forms of qualitative, quantitative, textual, image, and sound data today. The ease of expressing the results of an algorithm in human language is an essential condition for its use. J. P. Benzécri (1976), in L’Analyse des Données, I La Taxonomie-Les Peurs Enfantines, when referring to a classification tree constructed to represent the structure of a dataset related to children’s fears, wrote: 

"4. Validité d’une interprétation verbale. Nous voici parvenus, non-sens peine, à munir d’une légende la figure produite par l’ordinateur. Que vaut cette légende? En quel sens peut-on dire qu’un nom est bien choisi pour une classe? De quelle utilité peut être un tel nom? Le nom doit cerner, définir la classe: il doit à la fois s’accorder avec le contenu de cette classe……”.

With this Special Issue, in addition to targeting new, innovative methods and relevant applications of data analysis, contributions covering solutions for interpretation problems or theoretical constructions that may lead to general formulations of interpretation problems in the context of multivariate data analysis are sought, namely:

• Generalization of biplots for three or more modes to d > 3 dimensions;
• Cluster interpretations;
• Interpretability of algorithms;
• Results meaning and interpretation theory;
• Software: R or Python packages for new algorithms;
• Trees comparison;
• Statistical Modeling.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
