Masters of Data Science
RMIT University, Melbourne
Instead of just saying "Completed Masters of Data Science", let's test the study by its own medicine and evaluate the performance. Program gave me the Class labels as grades on my courses like High Distinction, Distinction..., unfortunately i got only these two. Created Classification Models and justified the grades. I have a micro mini dataset of my courses, 15 records, class is imbalanced, its "unfortunate" that i got more HD's (11 HD and 4 D), so used Synthetic Minority Oversampling Technique to balance it, did feature selection using information gain, gain ratio and chi-squared, and selected features using chi-squared which gave more importance, and created fused learners with AdaBoostM1, LogitBoost, RandomForest, Multilayer Perceptron and Naive Bayes. I am more interested in my False Negatives and i wish zero False Positives, all my models gave me Zero FP, i wished 2 FN's, in two more of my courses i felt deserved to get HD's, Naive Bayes didn't help me, Neural Networks said me, you can have One, but i liked AdaBoostM1, LogitBoost and RF, they said here you go with 2, based on voting with 3 classifiers, i accepted it. and i liked Matthews Correlation Coefficient which considers all and gave me 0.65 in all three classifiers.
