Question: What is the purpose of the \'gamma\' parameter in the RBF kernel of SVM?

Options:

Correct Answer: To define the influence of a single training example

Solution:

The \'gamma\' parameter in the RBF kernel controls the influence of a single training example, affecting the decision boundary\'s shape.

What is the purpose of the 'gamma' parameter in the RBF kernel of SVM?

Step 1: Understand that SVM stands for Support Vector Machine, which is a type of machine learning model used for classification tasks.
Step 2: Know that the RBF kernel (Radial Basis Function kernel) is a way to transform data into a higher dimension to make it easier to classify.
Step 3: Learn that the 'gamma' parameter is a setting in the RBF kernel that determines how much influence a single training example has on the model.
Step 4: Realize that a low 'gamma' value means that each training example has a far-reaching influence, leading to a smoother decision boundary.
Step 5: Understand that a high 'gamma' value means that each training example has a close influence, resulting in a more complex and wiggly decision boundary.
