ISYE 6501 - Introduction to Analytics Weeks 1 – 7 Combined Frequent Exam Questions Correctly Answered Support Vector Machine (SVM) - ANSWER Supervised learning classification tool and algorithm that seeks a dividing hyperplane for any number of dimensions can be used for regression or classification. Margin of Error (SVM) - ANSWER A small margin for error reduces your chances of misclassifying known data points but increases your chances of misclassifying unknown data points. ...

ISYE 6501 - Midterm 2 EXAM QUESTIONS WITH VERIFIED SOLUTIONS 100% LATEST UPDATE When might overfitting occur - ANSWER when the # of factors is close to or larger than the # of data points causing the model to potentially fit too closely to random effects Why are simple models better than complex ones - ANSWER less data is required; less chance of insignificant factors and easier to interpret What is forward selection - ANSWER we select the best new factor and see if it's good ...
