Due to the diversity of sources, a large amount of data is being produced and also has various
problems including mislabeled data, missing values, imbalanced class labels, noise and high
dimensionality. In this research article, we proposed a novel framework to address high
dimensionality issue with feature reduction to increase the classification performance of various
lazy learners, rule-based induction, bayes, and tree-based models. In this research, we proposed
robust Quarter Feature Selection (QFS) framework based on Symmetrical Uncertainty Attribute
Evaluator. Our proposed technique analyzed with Six real world datasets. The proposed
framework , divide whole data space into 4 sets (Quarters) of features without duplication. Each
such quarter has less than or equals 25 % features of whole data space. Practical results recorded
that, one of the quarter, sometimes more than one quarter recording improved accuracy than the
already available feature selection methods in the literature. In this research, we used filter-based
feature selection methods such as GRAE, IG, CHI-SQUARE (CHI 2), Relief to compare the
quarter of features produced by proposed technique.
