Topographic NMF for Data Representation
IEEE Transactions on Cybernetics, 2014Nonnegative matrix factorization (NMF) is a useful technique to explore a parts-based representation by decomposing the original data matrix into a few parts-based basis vectors and encodings with nonnegative constraints. It has been widely used in image processing and pattern recognition tasks due to its psychological and physiological interpretation ...

Data Representations in Learning
1996This paper examines the effect of varying the coarse-ness (or fine-ness) in a data representation upon the learning or recognition accuracy achievable. This accuracy is quantified by the least probability of error in recognition or the Bayes error rate, for a finite-class pattern recognition problem.

On the representation of data types
1981Representations of data types are presented, independently of the specification method used, by means of a generalization of the derivor concept, in a way that permits handling iteration and/or recursion, without losing the property of being closed under composition.

Context representation of product data
ACM SIGecom Exchanges, 2003This paper investigates the context representation of ad hoc product data that distribute in different semantic communities especially in small and medium sized enterprises through the analysis of the problems in extracting, mediating and comparing product contexts.

Information processing systems use a two-state technique. Information processed by them must be converted into symbols which can be understood and manipulated by these systems. The operation which consists of transforming the data into binary digits is called coding (also, encoding, or data coding).

Representation systems for data exchange
Proceedings of the 15th International Conference on Database Theory, 2012The notion of representation systems describes structures that are algebraically closed under queries. It has recently been realized that representation systems are highly relevant also in the context of data exchange. We extend the notion of representation system to encompass data exchange mappings and their composition.

Structure and representation of documents and data
Proceedings IEEE COMPCON 97. Digest of Papers, 2002The growth of the Internet has brought society at large a lot closer together. A vast amount of data, which was once accessible only to a select few, has become accessible to a much wider audience. Three important aspects of the data are the richness of its structure, its searchability and its representation.

Designing Palpable Data Representations
2020This paper discusses a multisensory approach to data representation with a specific focus on haptic media. In this, I provide a philosophical and methodological overview of my design process informed by the following themes and topics: 1) the haptic subject; 2) touch as political; 3) co-formed knowledge; and 4) arts-based research methods. The overview

Data representations for mobile devices
2007 International Conference on Parallel and Distributed Systems, 2007Data sharing and synchronisation involving mobile devices has been a significant challenge to research. The methods for tracking changes and conflicts often require the involvement of a server or desktop PC with the available storage or processing power to do so, reducing the flexibility and potential of mobile device applications.
