Questions & Step-by-Step Solutions

What does the term 'margin' refer to in the context of SVM?
  • Step 1: Understand that SVM stands for Support Vector Machine, which is a type of algorithm used for classification tasks.
  • Step 2: In SVM, we have different classes of data points that we want to separate.
  • Step 3: The 'margin' is the space between the closest data points from each class.
  • Step 4: The goal of the SVM algorithm is to make this margin as wide as possible.
  • Step 5: A wider margin means better separation between the classes, which helps in making more accurate predictions.
