Support Vector Machines Overview - Problem Set

Q. In a binary classification problem, what does a high value of the margin indicate?

Solution

A high value of the margin indicates that the model is more robust to noise and is likely to generalize better.

Correct Answer: C — The model is more robust to noise

Q. In the context of SVM, what does 'margin' refer to?

Solution

The margin in SVM refers to the distance between the closest data points of different classes, which the algorithm aims to maximize.

Correct Answer: A — The distance between the closest data points of different classes

Q. In which real-world application is SVM commonly used?

Solution

SVM is widely used in image recognition tasks, where it effectively classifies images based on their features.

Correct Answer: A — Image recognition

Q. What is the role of the soft margin in SVM?

Solution

The soft margin allows for some misclassification, which helps improve the model's generalization to unseen data.

Correct Answer: A — To allow some misclassification for better generalization

Q. Which evaluation metric is most appropriate for assessing the performance of an SVM classifier?

Solution

Accuracy is a common evaluation metric for classification tasks, including those performed by SVM classifiers.

Correct Answer: B — Accuracy

Q. Which of the following scenarios is SVM particularly well-suited for?

Solution

SVM is particularly well-suited for classifying linearly separable data, as it can effectively find the optimal separating hyperplane.

Correct Answer: B — Classifying linearly separable data
