Asymptotic behaviors of nearest neighbor kernel density estimator in left-truncated data
Kernel density estimators are the basic tools for density estimation in non-parametric statistics. The k-nearest neighbor kernel estimators represent a special form of kernel density estimators, in which the bandwidth is varied...
Predicting Corporate Financial Distress Using Data Mining Techniques An Application in Tehran Stock Exchange
to predict financial distress of Iranian firms, with four techniques: support vector machines, artificial neural networks (ANN), k-nearest neighbor and naïve bayesian classifier by using accounting information of the firms for two years prior to financial...
Fuzzy Discrete Correlation for Document Clustering
this information. A new method that uses neighbor and link concepts has more suitable performance than previous methods in this field. Two documents are neighbors if their similarity is more than a defined threshold. If they are neighbors, neighbor matrix element...
Neighbor Based Topology Control Protocol for Prolonging the Lifetime of Ad Hoc Networks
Topology control, wherein nodes adjust their transmission ranges to conserve energy is an important feature in wireless ad hoc networks. In this paper we propose a power control protocol based on neighbor detection for conserving energy...
