Sentence examples for internal variances from inspiring English sources

On the other hand, the ellipses of dispersion indicated that clusters 3 and 7, even though they account for the highest number of populations, had lower internal variances.

The analysis of microarray gene expression data has shown that distributions of d and total and internal variances are expression dependent.

The aim is to find a solution that minimises the internal variance within clusters relative to a specified centroid (e.g. the medoid, or mean in the kmeans partitioning) and maximises the distance between cluster centroids.

White marble was not taken into account for the bioreceptivity index, since ANOVA results of microbial growth showed greater internal variance among replicates than between these and the other lithotypes.

Beta1AR, beta3AR, and HIVi are very small datasets in our comparison; thus, it seems probable that the poor results of the Bayesian approach (a poor approximation of the (mathcal {S}) value) were caused by the high internal variance in the dataset rather than because the Bayesian approach was actually worse than the grid search method.

These are: sampling variance, split variance, testing set size, and internal variance.

Finally, internal variance refers to uncertainty associated with classifier instability (i.e., different training datasets lead to different signatures) and increases as training set size decreases [30], [36].

The repeated 10-fold cross-validation essentially eliminates split variance by using many splits and averaging over them, and furthermore it reduces internal variance by using more sample for training than holdout (under typical training-testing split ratios).

Finally, while testing set size variance is larger in the repeated 10-fold estimator than the holdout, the combination of higher split and internal variance makes overall the holdout to have higher variance and to be less powerful than repeated 10-fold cross-validation in many practical situations.

The outlier group is not a cluster in a statistical sense, because of the amount of internal variance on general satisfaction and benefit of treatment.

As we used pooled samples of each four culture replicates in this first experiment, no internal variance within the respective groups was calculated.
