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 ...

Identify whether the task required is supervised or unsupervised learning: Deciding whether to issue a loan to an applicant based on demographic and financial data (with reference to a database of similar data on prior customers). - Supervised - Unsupervised -:- Supervised This is supervised learning, because the database includes whether the loan was approved or not. Identify whether the task required is supervised or unsupervised learning: Printing of custom discount coupons at t...

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 subset of training points in the decision functio...
