Student Performance Dataset - Classification and Regression

Updated: Nov 3, 2021




Description :


This dataset contains information about student performance in secondary education of two Portuguese schools. The data attributes are student grades, demographic, social and school related features) and it was collected by using school reports and questionnaires. Two datasets are provided regarding the student performance in two subjects: Mathematics (mat) and Portuguese language (por). The two datasets were modeled under binary/five-level classification and regression tasks. Important note: the target attribute G3 has a strong correlation with attributes G2 and G1. This occurs because G3 is the final year grade (issued at the 3rd period), while G1 and G2 correspond to the 1st and 2nd period grades. It is more difficult to predict G3 without G2 and G1, but such prediction is much more useful (see paper source for more details).


Recommended Model :


Algorithms to be used, regression, random forest, Support Vector Machines, Logistic regression, decision tree, naive bayes etc.


Recommended Projects :


To predict the student performance based on the student related information.
