The Random Forest algorithm is an ensemble technique that can achieve high accuracy on classification and regression with minimal tuning of parameters. This paper analyzes the effectiveness of the Random Forest classification algorithm under decreasing randomness in the bootstrap sampling procedure, in increasing tournament size, and in tournament participant selection.
The purpose of this study was to analyze validity and reliability of Utrecht Nine-item Work Engagement Scale (UWES-9). Concerning its purpose, the study was applied and regarding data collection method, it was a descriptive study. The population of the study consisted of all Kurdistan Education Organization staff (200 subjects) with a sample size of 127, selected through simple random samp...
We develop methods for performing filtering and smoothing in non-linear non-Gaussian dynamical models. The methods rely on a particle cloud representation of the filtering distribution which evolves through time using importance sampling and resampling ideas. In particular, novel techniques are presented for generation of random realisations from the joint smoothing distribution and for MAP est...
We propose a general unsupervised multiscale featurebased approach towards image segmentation. Clusters in the feature space are assumed to be properties of underlying classes, the recovery of which is achieved by the use of the mean shift procedure, a robust non-parametric decomposition method. The subsequent classification procedure consists of Bayesian multiscale processing which models the ...
In this paper, a new estimate of exponential type of auxiliary information to help simple random sampling without replacement of the finite population mean is introduced. This new estimator with a few other estimates using two real data sets are compared with the mean square error.
