in this paper, we obtain the general solution and the generalized  hyers--ulam--rassias stability in random normed spaces, in non-archimedean spacesand also in $p$-banach spaces and finally the stability viafixed point method for a functional equationbegin{align*}&d_f(x_{1},.., x_{m}):= sum^{m}_{k=2}(sum^{k}_{i_{1}=2}sum^{k+1}_{i_{2}=i_{1}+1}... sum^{m}_{i_{m-k+1}=i_{m-k}+1}) f(sum^{m}_{i=1...

We investigate, theoretically and empirically, the effectiveness of kernel K-means++ samples as landmarks in the Nyström method for low-rank approximation of kernel matrices. Previous empirical studies (Zhang et al., 2008; Kumar et al., 2012) observe that the landmarks obtained using (kernel) K-means clustering define a good lowrank approximation of kernel matrices. However, the existing work d...

Cluster analysis may be performed when one wishes to group similar objects into a given number of clusters. Several algorithms are available in order to construct these clusters. In this talk, focus will be on the generalized k-means algorithm which has the classical k-means procedure as well as the k-medoids algorithm as particular cases. Among the outputs of these clustering techniques, a cla...

Crown imperial scattered according to soil structure and organic matter in Zagros regions in Ilam. This plant has been performed an important role in the beautification of environment, tourist attraction and providing of plant essential oils which are used for the production of medicines. The current research was carried out to evaluation spatial distribution pattern of Fritillaria imperialis i...

parameter estimation is an important task in the modeling, classification, and detection of radar clutters. radar clutters have stochastic characteristics. therefore, statistical distributions are usually used to describe the features of clutters better. k distribution is one of the most common models utilized to the simulation of clutters. this distribution, which consists of scale and shape p...

In K-edge decomposition imaging for the multienergy system with photon counting detectors (PCDs), energy bins significantly affect intensity of extracted signal. Optimized can provide a better signal to improve quality images and have potential reduce amount contrast agents. this article, we present Gaussian spectrum selection method (GSSM) which extract an optimized by optimizing compared conv...

Road pavement is a supporting factor for national development, especially in the distribution of trade goods and services as well movement human mobility. maintenance needs to be done regularly so that road always good condition, but weather loads are things cause damage. damage generally categorized into cracks, alligator cracks potholes. The purpose this research utilize image processing dete...
