“…The widely used approaches from the reviewed articles include regression [34,44,45,83,86,89,110,126,127], analysis of variance (ANOVA) [27,79], GA [55,83], Las Vegas filter [60,78], Pearson coefficient [79], Cramer's V correlation coefficients [85,87], and so on. Clustering [38,90,101,126], aggregation [34,87], and sampling [82] based approaches were applied to reduce the data numerosity. PCA or the modified PCA [64,65,83,92,94], and multi-dimensional scaling [84] were employed to compress the representation of the original data.…”
