scott and szewczyk in technometrics, 2001, have introduced a similarity measure for twodensities f1 and f2 , by1, 21 21 1 2 2( , ), ,f fsim f ff f f f< >=< >< >wheref1, f2 f1(x, θ1)f2(x, θ2)dx.+∞−∞< >=∫sim(f1, f2) has some appropriate properties that can be suitable measures for the similarity of f1 and f2 .however, due to some restrictions on the value of parameters and the kind of densities, ...

The level of sequence similarity that implies similarity in protein structure is well established. Recently, many groups proposed thresholds for similarity in sequence implying similarity in enzymatic function. All previous results suggest the strong conservation of enzymatic function above levels of 50% pairwise sequence identity. Here, I argue that all groups substantially overestimated the c...

Palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. Texture is one of the most important features extracted from low resolution images. In this paper, a new local descriptor, Local Composition Derivative Pattern (LCDP) is proposed to extract smartly stronger...

We suggest to define objective probabilities by similarity-weighted empirical frequencies, where more similar cases get a higher weight in the computation of frequencies. This formula is justified intuitively and axiomatically, but raises the question, which similarity function should be used? We propose to estimate the similarity function from the data, and thus obtain objective probabilities....

This paper presents a method for semantic classication of onomatopoetic words like “ひゅーひゅー (hum)” and “からん ころん (clip clop)” which exist in every language, especially Japanese being rich in onomatopoetic words. We used a graph-based clustering algorithm called Newman clustering. The algorithm calculates a simple quality function to test whether a particular division is meaningful. The quality f...

Abstract. Hillslope similarity is an active topic in hydrology because of its importance improving our understanding hydrologic processes and enabling comparisons paired studies. In this study, we propose a holistic bottom-up hillslope clustering based on region's integrative hydrodynamic response quantified by the seasonal changes groundwater levels ΔP. The main advantage ΔP ability to capture...
