Determining property relevance in concept formation by computing correlation between properties [chapter]

João José Furtado Vasco
1998 Lecture Notes in Computer Science  
This relevance is computed through the account of the property correlation with other ones and it is used by the concept quality function in order to improve predictive accuracy.  ...  We propose a method to incrementally compute and use, during the concept formation, the relevance of a concept property.  ...  In this paper, we propose a method to compute the relevance of a concept property based on file correlation between properties of file entities covered by the concept.  ...

of semantically correlating concepts thus reducing the concept match space.  ...  The proposed ontology matching system is adaptive in nature because of the cognitive based knowledge expression and the computational overhead of generating alignments is improved by forming quality clusters  ...  Hence by determining similarity between concepts, relations and their correlation degree, concepts with rich semantics are determined which helps in forming better alignments.  ...

Semantics-Empowered Big Data Processing with Applications

Krishnaprasad Thirunarayan, Amit Sheth
2015 The AI Magazine  
To handle velocity, we seek to use continuous semantics capability to dynamically create event or situation specific models and recognize relevant new concepts, entities and facts.  ...  We discuss the nature of big data and address the role of semantics in analyzing and processing big data that arises in the context of physical-cyber-social systems.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the NSF.  ...

Overview of imaging science

R. N. Beck
1993 Proceedings of the National Academy of Sciences of the United States of America  
The traditional disciplines of science are grounded in the observation and measurement of object properties.  ...  Recent advances in digital computer technology have spawned numerous computer-based imaging systems that extend the range of observation and measurement into realms that would otherwise be inaccessible  ...  As has been suggested already, image formation, in the most general sense of the term as it is used here, involves the concept of the image as a mapping of some detectable object property into image space-i.e  ...

Contextual-Based Approach to Reduce False Positives

Nadjah CHERGUI, Narhimene Boustia
2019 IET Information Security  
The high rate of false positive alerts generated by the intrusion detection system (IDS), raises a crucial problem in the face of the security operator to differentiate between true attacks and failed  ...  NOC-IDS aims in general to filter false positive alerts and to figure out relevant alerts, and helping the security operator to analyse relevant ones.  ...  It provides a tractable algorithm for computing the subsumption relation between the concepts and the inheritance of properties and thus it is used in practical case [23] .  ...

An efficient coding approach to the debate on grounded cognition

Abel Wajnerman Paz
2018 Synthese  
In this case, the predictions that must be tested are related to the implementation of specific computational operations and task parameters presupposed by the relevant efficient coding model.  ...  I propose that modal format can be identified by determining the relation between intrinsic structure and perceptual processing and claim that efficient coding models can be useful precisely to understand  ...  This suggests that sparse codes are not only implemented by visual areas but also correlated with the statistical properties of natural visual signals.  ...

Predictability of spatio-temporal patterns in a lattice of coupled FitzHugh-Nagumo oscillators

M. Grace, M.-T. Hutt
2013 Journal of the Royal Society Interface  
As a function of drift speed and desynchronization, we observe systematically different routes towards fully established patterns, as well as strikingly different correlations between cell properties and  ...  We show that the predictability of spatio-temporal patterns from cell properties contains important information on the pattern formation process as well as on the underlying dynamical system.  ...  This project was funded by the Deutsche Forschungsgemeinschaft (DFG; grant no.

Bridging the Gap between Similarity and Causality: An Integrated Approach to Concepts

Corinne L Bloch-Mullins
2017 British Journal for the Philosophy of Science  
A growing consensus in the philosophy and psychology of concepts is that while theories such as the prototype, exemplar, and theory theories successfully account for some instances of concept formation  ...  I put forth a sketch of an integrated model of concept formation and application, which rejects this shared assumption and satisfies the explanatory desiderata I discuss.  ...  In order to satisfy it, models of concept formation and application should include the effects of factors such as goals and background knowledge on the selection of relevant properties (and correlations  ...
