ISYE 6501 Final Questions and Answers Already Passed Support Vector Machine A supervised learning, classification model. Uses extremes, or identified points in the data from which margin vectors are placed against. The hyperplane between these vectors is the classifier SVM Pros/Cons Pros: It works really well with a clear margin of separation It is effective in high dimensional spaces. It is effective in cases where the number of dimensions is greater than the number of samples. It uses a subse...

Logistic regression is different from standard linear regression in that: correct answers It does not have an error term; The response variable is not normally distributed; It models probability of a response and not the expectation of the response Logistic regression models correct answers The probability of a success given a set of predicting variables In logistic regression correct answers The estimation of the regression coefficients is based on maximum likelihood estimation Using t...

What do descriptive questions ask? What happened? (e.g., which customers are most alike) What do predictive questions ask? What will happen? (e.g., what will Google's stock price be?) What do prescriptive questions ask? What action(s) would be best? (e.g., where to put traffic lights) What is a model? Real-life situation expressed as math. What do classifiers help you do? differentiate What is a soft classifier and when is it used? In some cases, ther...
