Imputing Missing Values Using Support Variables with Application to Barley Grain Yield

Erbilen, Mustafa (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2019)

In any data collection process, regardless of the sampling method, missing data values are encountered due to many different reasons. Depending on the amount of missing data the results to be obtained from the analysis of ...
Post-Pruning Decision Tree Algorithms Based on Bayes Minimum Risk and Loss Minimization to Combat Over-Fitting Problem

Mohamed, Ahmed Mohamed Ahmed (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2018)

Pruning is applied in order to combat over-fitting problem where the tree is pruned with the goal of identifying decision tree with the lowest error rate on previously unobserved instances. Post-pruning approach is one of ...
