2001 Lecture Notes in Computer Science  
This paper presents a computer simulation of context effects on problem solving with AMBR -a model of human analogy-making.  ...  It also shows that the timing of this perception is important: while the context element may have crucial influence during the initial stages of problem solving it has virtually no effect during the later  ...  Acknowledgments We would like to thank the AMBR research group for the stimulating environment and especially Alexander Petrov for his work on AMBR and the knowledge bases that are used in these simulations  ...

Privacy-preserving smart meter control strategy including energy storage losses

Ramana R. Avula, Tobias J. Oechtering, Daniel Mansson

Computational models of analogy

Dedre Gentner, Kenneth D. Forbus
2010 Wiley Interdisciplinary Reviews: Cognitive Science  
In the past 25 years, this area has progressed rapidly, fueled by strong collaboration between psychologists and Artificial Intelligence (AI) scientists, with contributions from linguists and philosophers  ...  However, computational models still differ in their focus, with some aimed at capturing the range of analogical phenomena at the cognitive level and others aimed at modeling how analogical processes might  ...  DUAL has been used to model priming and context effects on problem-solving. The Companions cognitive architecture 75 is based on structure-mapping models.  ...
