Harmonic mean for subspace selection
2008 19th International Conference on Pattern Recognition, 2008Under the homoscedastic Gaussian assumption, it has been shown that Fisherpsilas linear discriminant analysis (FLDA) suffers from the class separation problem when the dimensionality of subspace selected by FLDA is strictly less than the class number minus 1, i.e., the projection to a subspace tends to merge close class pairs.

The emotional meaning of harmonic intervals
Cognitive Processing, 2008The present study reexamines the hypothesis that there exist emotional attributions specific to simple musical elements. In Experiment 1, groups of participants, with varying musical expertise, rated the emotional meaning of four natural intervals heard as two harmonic sine waves.

A Diophantine equation with the harmonic mean
Periodica Mathematica Hungarica, 2019Let $$f\in \mathbb {Q}[x]$$ be a polynomial without multiple roots and $$\deg {f}\ge 2$$. We give conditions for $$f=x^2+bx+c$$ under which the Diophantine equation $$2f(x)f(y)=f(z)(f(x)+f(y))$$ has infinitely many nontrivial integer solutions and prove that this equation has infinitely many rational parametric solutions for $$f=x^2+bx$$ with nonzero ...

The harmonic or geometric mean
ACM SIGARCH Computer Architecture News, 2006For several decades, computer scientists have been arguing which mean is more appropriate for summarizing computer performance: the harmonic or the geometric. We show that many test cases used in the past to discredit one mean or the other are either artificial or incidental.

Summary: Harmonic mean is a conservative average, which is widely used to aggregate central tendency data. In the existing literature, the harmonic mean is generally considered as a fusion technique of numerical data information. In this paper, we investigate the situations in which the input data are expressed in fuzzy values and develop some fuzzy ...
