Language of Preference Formulae
Nedbal, Radim
2012 - English There is a need for handling preferences in relational query languages that arises naturally in real-world applications dealing with possible choices generated by the current state of the world captured in the relational data model. To address this problem, we propose a fully declarative language for encoding preferences conditional on the current state of the world represented as a relation database instance. Being based purely on the qualitative type of information about the preference model, the language is intuitive and leads to a exible approach for specifying the most desirable choices of autonomous systems that act on behalf of their designers. Throughout the paper, we use an example of a control support system for a bank surveillance to motivate the need for our framework and to illustrate it. Keywords: conflicting preferences; relational data model; database query Available at various institutes of the ASCR Language of Preference Formulae

Classification Methods for Brain-Computer Interface
Bobrov, P.; Frolov, A. A.; Húsek, Dušan
2011 - English The performance of four classifiers for Brain Computer Interface (BCI) systems based on multichannel EEG recordings is tested in this work. The classifiers are designed to distinguish EEG patterns corresponding to performance of several mental tasks. It is shown that relatively simple classifiers based on the Bayesian approach are comparable in classification accuracy with more sophisticated classifiers based on Common Spatial Patterns and Common Tensor Discriminant Analysis Keywords: brain computer interface; BCI; EEG; Bayesian classifier; common spatial patterns; CSP; common tensor discriminant analysis; CTDA; classification accuracy Available on request at various institutes of the ASCR Classification Methods for Brain-Computer Interface
