Most texts have a large number of features. However, the features contained in the text mostly have a low level of relevance and even caontain noise which can later reduce the accuracy of the results. Feature selection is used to reduce the dimensions of feature space by weighting all features then features with lower weights than treshold will be eliminated. It aims to improve the accuracy and…
There are so many prospective workers with the same educational background, but not necessarily in accordance with the required company position and not necessarily they have the same expertise. To minimize the occurrence of errors, it can be done by making a decision-making system (DSS) to provide these recommendations.
