Classifier Combinations: Implementations and Theoretical Issues

Abstract: Much work has been done in the past decade to combine decisions of multiple classifiers in order to obtain improved recognition results. Many methodologies have been designed and implemented for this purpose. This article considers some of the current developments according to the structure of the combination process, and discusses some issues involved in each structure. In addition, theoretical investigations that have been performed in this area are also examined, and some related issues are discussed.

Multiwavelets denoising using neighboring coefficients

Abstract: Multiwavelets give better results than single wavelets for signal denoising. We study multiwavelet thresholding by incorporating neighboring coefficients. Experimental results show that this approach is better than the conventional approach, which only uses the term-by-term multiwavelet denoising. Also, it outperforms neighbor single wavelet denoising for some standard test signals and real-life images. This is an extension to Cai and Silverman's (see Sankhya: Ind. J. Stat. B, pt.2, vol.63, p.127-148, 2001) work.

Seasonal thermal energy storage with heat pumps and low temperatures in building projects—A comparative review

Abstract: Application of seasonal thermal energy storage with heat pumps for heating and cooling buildings has received much consideration in recent decades, as it can help to cover gaps between energy avail ...

Habit-forming actions of nomifensine in nucleus accumbens.

Abstract: Rats learned to lever-press when reinforced with response-contingent microinfusions of the dopamine uptake inhibitor nomifensine (1.7 nmol per injection) into the ventro-medial (shell) region of nucleus accumbens septi (NAS). The drug was not effective when similar injections were given either in random relation to lever-pressing, into the more dorso-lateral (core) region of NAS, or into the frontal cortex. Cocaine was also effective in NAS, but considerably less so. These data suggest that response-contingent dopamine uptake blockade within the NAS is sufficient to establish and maintain instrumental response habits.
