Support Vector Machines (SVM)

• Purpose: Classification and regression.
• Mechanism: Establishes decision boundaries with maximum margin.
• Margin: The thickness of the decision boundary, large margin minimizes overfitting.
• Support Vectors: Data points that the margin directly affects.
• Kernel Trick: Projects non-linear data into...
