Bridging real-world contexts and units of behavioral variations by composite layers

Tetsuo Kamina, Tomoyuki Aotani, Hidehiko Masuhara
2012 Proceedings of the International Workshop on Context-Oriented Programming - COP '12  
In this proposal, only atomic layers (layers that directly correspond to a context) can be explicitly controlled by linguistic operations for layer activation.  ...  This extension bridges the gap between contexts and units of behavioral variations that complicates programs written in COP languages.  ...  Problem description Layer-based COP languages provide a mechanism to modularize context-dependent behaviors in a layer and to dynamically switch between layers.  ...

Modeling Contexts for Business Process Oriented Knowledge Support [chapter]

Marielba Zacarias, Artur Caetano, H. Sofia Pinto, José Tribolet
2005 Lecture Notes in Computer Science  
We focus on actors' capabilities for handling several action contexts. Interaction contexts are defined as the supporting components of actors' interactions related to business processes.  ...  We relate the defined concepts and propose a business process oriented and context-based modeling approach which aims to provide a richer, efficient and flexible semantics, capable of better representing  ...  At some specific time frame, actors' information requirements depend of the active action context.  ...

switch behaviors.  ...  Thus, in existing COP languages, context-related concerns can easily be tangled within a piece of layer activation code.  ...  Related Work Non Layer-based COP Languages Some COP languages do not use layers as units for the modularization of context-dependent variations of behavior.  ...

Reflective layer activation in ContextL

Pascal Costanza, Robert Hirschfeld
2007 Proceedings of the 2007 ACM symposium on Applied computing - SAC '07  
Expressing layer dependencies in Context-oriented Programming is cumbersome because until now no facility has been introduced to control the activation and deactivation of layers.  ...  This allows expressing complex application-defined dependencies between layers where the activation or deactivation of a layer requires the activation or deactivation of another one.  ...  Acknowledgements We thank Nick Bourner, Johan Brichau, Drew Crampsie, Brecht Desmet, Attila Lendvai, and Igor Plekhov for fruitful discussions and valuable contributions.  ...

An Introduction to Context-Oriented Programming with ContextS [chapter]

Robert Hirschfeld, Pascal Costanza, Michael Haupt
2008 Lecture Notes in Computer Science  
Context-oriented Programming, or COP, provides programmers with dedicated abstractions and mechanisms to concisely represent behavioral variations that depend on execution context.  ...  By treating context explicitly, and by directly supporting dynamic composition, COP allows programmers to better express software entities that adapt their behavior late-bound at run-time.  ...  Acknowledgements We thank Marcus Denker, Tudor Girba, Robert Krahn, Dave Thomas, and Jan Wloka for their fruitful discussions and valuable contributions, and Ralf Lämmel for his patience.  ...

Context-Oriented Software Development with Generalized Layer Activation Mechanism [chapter]

Tetsuo Kamina, Tomoyuki Aotani, Hidehiko Masuhara, Tetsuo Tamai

Creation of domain-specific languages for executable system models with the Eclipse Modeling Project

Sven Jager, Ralph Maschotta, Tino Jungebloud, Alexander Wichmann, Armin Zimmermann
2016 2016 Annual IEEE Systems Conference (SysCon)  
This paper proposes a workflow for designing complex systems by using domain-specific models which may combine structural and behavioral aspects.  ...  The latter approach is easier and more efficient but restrictive. The success of this approach strongly relies on the support of domain-specific tools.  ...  ACKNOWLEDGMENTS This paper is based on work funded by the Federal Ministry for Education and Research of Germany under grant number 01S13031A.  ...

Thalamocortical contribution to solving credit assignment in neural systems [article]

2021 arXiv   pre-print
The faster timescale establishes contextual associations to enable rapid behavioral flexibility while the slower one enables generalization to new contexts.  ...  , environmental context with rewards is ambiguous.  ...  The corticothalamic structures can then consolidate these BG-guided flexible switching behaviors via our proposed network motif and the switching becomes less BG-dependent.  ...

Human EEG Uncovers Latent Generalizable Rule Structure during Learning

A. G. E. Collins, J. F. Cavanagh, M. J. Frank
2014 Journal of Neuroscience  
Behavioral studies show that humans impute structure into simple learning problems, even when this tendency affords no behavioral advantage.  ...  Both neural markers were predictive of participants' ability to subsequently generalize rule structure to new contexts.  ...  This abstract representation, not tied to the context in which the rule is learned or applied, enables the building of a repertoire of rules that can be generalized to new contexts (Collins and Koechlin  ...

The interaction between competition, learning, and habituation dynamics in speech perception

Leonardo Lancia, Bodo Winter
2013 Laboratory Phonology  
Our model can account for these results and for a surprising finding, namely that the initial presentation order affected responses even late in the experiment.  ...  Here, we propose a unified dynamical account of three types of behavior that are usually studied in isolation: short-term perceptual competition, long-term perceptual habituation, and even longer-term  ...  We want to thank Martine Grice, Doris Mücke, and the anonymous reviewers for helpful comments and suggestions, and Kayla Hewitt for proofreading.  ...
