Two experiments explore the effects of mood on category learning. In the first experiment subjects were put into either a negative or a neutral mood before completing one of two category-learning tasks. Negative mood briefly impaired rulebased category learning but this impairment did not persist throughout the task. Negative mood did not influence nonrule-based learning. In a second study subj...

The compound nouns are freely composed in Korean, since it is possible to concatenate independent nouns without a postposition. Therefore, the systems that handle compound nouns such as machine translation and information retrieval have to decompose them into single nouns for the further correct analysis of texts. This paper proposes the GECORAM (GEneralized COmbination of Rule-based learning A...

Using New Keynesian models, we compare Friedman’s k-percent money supply rule to optimal interest rate setting, with respect to determinacy, stability under learning and optimality. First we review the recent literature: open-loop interest rate rules are subject to indeterminacy and instability problems, but a properly chosen expectations-based rule yields determinacy and stability under learni...
