On Common Factor and Principal Component Representations of Data: Implications for Theory and for Confirmatory Replications

Keith F. Widaman
2018 Structural Equation Modeling  
Researchers are often advised to use either FA or PCA in exploratory rounds of data analysis to understand and refine the dimensional structure of a domain before moving to structural equation modeling  ...  Determinate in most respects, a heretofore unacknowledged, pernicious indeterminacy of PCA is demonstrated: the indeterminacy between PCA structural representations and the correlational structures from  ...  On Common Factor and Principal Component Representations of Data: Implications for Theory and for Confirmatory Replications The first paper on common factor analysis (FA) was published over a century  ...

The Role of Synthetic Geometry in Representational Measurement Theory

Uta Wille
1997 Journal of Mathematical Psychology  
Because geometric representations support the interpretation of data and help to reveal dependencies of attributes, measurement theory should consider geometric spaces as representing structures as well  ...  We show that, within such a broader paradigm of representational measurement theory, synthetic geometry can play a twofold role which enriches the theory and the possibilities of data interpretation.  ...  Because geometric representations support the interpretation of data and help to reveal dependencies of attributes, measurement theory should consider geometric spaces as representing structures as well  ...

Application of Graph Theory in Computer Science and Engineering

Rishi PalSingh, Vandana Vandana
2014 International Journal of Computer Applications  
This paper explores different concepts involved in graph theory and their applications in computer science to demonstrate the utility of graph theory.  ...  These applications are presented especially to project the idea of graph theory and to demonstrate its objective and importance in computer science engineering.  ...  To analyze the graph theory application in networking two areas are considered: graph based representation and network theory.  ...

Generative linguistics within the cognitive neuroscience of language

Alec Marantz
2005 The Linguistic Review  
Standard practice in linguistics often obscures the connection between theory and data, leading some to the conclusion that generative linguistics could not serve as the basis for a cognitive neuroscience  ...  The single generative engine within Minimalist approaches rejects dual routes to linguistic representations, including possible extra-syntactic strategies for semantic structure-building.  ...  Distributional data of the sort extractable from recorded utterances provide rich material for theories of representation.  ...

Hsiang-Ke Chao's Representation and structure in economics: the methodology of econometric models of the consumption function. London: Routledge, 2008, 176 pp

Christopher L. Gilbert
2010 Erasmus Journal for Philosophy and Economics  
It relates to a broad collection of less abstract approaches to the role of theory in which theory and structure become closely related concepts.  ...  Model structures can therefore only aspire to being partial representations, in the same way that a road map is, by design, a partial representation of the terrain.  ...  Both Schultz and Stone saw the role of theory as that of organizing data and structuring research.  ...

Sequential Pattern Mining and Deep Learning to Enhance Readability of Indonesian Text Summarization

Dian Sa'adillah Maylawati
2019 International Journal of Advanced Trends in Computer Science and Engineering  
This paper gives an opportunity to take a deeper look into how to design an efficient and effective text representation which can further enhance text summarization readability.  ...  Evidence from previous literatures shows that there are several studies which use Sequential Pattern Mining to extract representation of text for document clustering and classification of Indonesian text  ...  We would like to thank to Muhammad Ali Ramdhani as a Professor of Information Technology in UIN Sunan Gunung Djati Bandung who is willing to become an expert in evaluating and giving many suggestions for  ...

Ontology Structure of Elements for Web-based Natural Disaster Preparedness Systems

Chen-Huei Chou, Fatemeh Zahedi
2007 Americas Conference on Information Systems  
We provide a comprehensive review of the existing semi-structured data representation technologies and select the appropriate set for developing and representing the ontology structure.  ...  Web elements are identified based on the grounded theory approach using an inventory of 100 non-profit disaster websites and their numerous webpages.  ...  This work also shows how the synthesis of ontology, grounded theory, and semi-structured data representation technologies could make it possible to identify and code the ontology structure of web elements  ...

Does the Shannon bound really apply to all data structures?

A Valmari
2013 Proceedings of the Estonian Academy of Sciences  
Unlike in classical information theory, a representation scheme may be memory-optimal even if some object has more than one representation.  ...  Then we formalize the concept of data structure with the notion of "representation scheme" that is general enough to model the example system.  ...  The publication has definitely benefited a lot from the discussion and the amount of time and energy that the reviewers and the editor spent.  ...

Chi square tests demonstrated that subgoal structure exists within this set and that some structures occur more frequently than others. These results confirmed predictions from Study IA data.  ...  The second class of theories, called syntax implicit, suggest that no distinct syntactic representation is constructed, but rather that a semantic representation of the sentences meaning is constructed  ...
