ISYE 6501 Midterm 1 (2023/2024) Already Graded A Rows Data points are values in data tables Columns The 'answer' for each data point (response/outcome) Structured Data Quantitative, Categorical, Binary, Unrelated, Time Series Unstructured Data Text Support Vector Model Supervised machine learning algorithm used for both classification and regression challenges. Mostly used in classification problems by plotting each data item as a point in n-dimensional space (n is the number of features y...

Does a SVM classifier need to be a straight line? - No, SVM can be generalized using kernel methods that allow for nonlinear classifiers. Software has a kernel SVM function that you can use to solve for both linear and nonlinear classifiers Should you scale your data in a SVM model? - Yes, so the orders of magnitude are approximately the same. Data must be in bounded range. Common scaling: data between 0 and 1 a. Scale factor by factor b. Linearly What if it's not possible to separate ...

ISYE 6501 REAL MIDTERM EXAM | REAL EXAM QUESTIONS WITH CORRECT ANSWERS AS PER MARKING SCHEME Instructions Work alone. Do not collaborate with or copy from anyone else. You may use any of the following resources: One sheet(both sides) of handwritten (not photocopied, scanned, or printed) notes If any question seems ambiguous, use the most reasonable interpretation (i e don't be like Calvin): Instructors know about the issue in a private Piazza post afterwards. Good luck! 1...

Machine learning correct answers AI that learns predictive models from data; automates analytical model building Machine learning correct answers Uses algorithms that iteratively learn from data to allow computers to find hidden insight without being explicitly programmed Machine learning correct answers A computer program is said to learn from experience E with respect to some task T and some performance measure P. if its performance on T, as measured by P, improves with experience E S...
