### Support Vector Machine (SVM) is a type of algorithm used for:

• A.

Clustering

• B.

Regression

• C.

Classification

• D.

Dimensionality Reduction

C. Classification
Explanation
Support Vector Machine (SVM) is a type of algorithm used for classification. It is commonly used to categorize data points into different classes based on their features.

### In SVM, the objective is to find the hyperplane that has the:

• A.

Highest margin

• B.

Lowest margin

• C.

Highest accuracy

• D.

Lowest accuracy

A. Highest margin
Explanation
In SVM, the objective is to find the hyperplane that has the highest margin. The margin is the distance between the hyperplane and the closest data points of each class.

### The term "kernel" in SVM refers to:

• A.

A transformation function

• B.

A hyperparameter

• C.

A cost function

• D.

A regularization term

A. A transformation function
Explanation
The term "kernel" in SVM refers to a transformation function. Kernels are used to map data into a higher-dimensional space, making it easier to separate non-linearly separable data.

• 4.

### SVM can handle both linear and nonlinear data by using:

• A.

• B.

Feature Scaling

• C.

Kernels

• D.

Cross-Validation

C. Kernels
Explanation
SVM can handle both linear and nonlinear data by using kernels. Kernels allow SVM to transform the data into a higher-dimensional space, where linear separation becomes possible.

• 5.

### In SVM, data points that are closest to the hyperplane are called:

• A.

Support Vectors

• B.

Outliers

• C.

Nearest Neighbors

• D.

Decision Boundaries

A. Support Vectors
Explanation
In SVM, data points that are closest to the hyperplane are called support vectors. These points play a crucial role in defining the hyperplane and the margin.

• A.

Learning rate

• B.

Regularization strength

• C.

Kernel size

• D.

Number of clusters

B. Regularization strength
Explanation
The parameter C in SVM controls the regularization strength. It determines the trade-off between maximizing the margin and minimizing the training error.

### SVM aims to maximize the margin between:

• A.

Classes

• B.

Data points

• C.

Features

• D.

Clusters

A. Classes
Explanation
SVM aims to maximize the margin between classes. The margin is the space between the hyperplane and the closest data points of each class.

### The SVM decision boundary is determined by the data points that are:

• A.

Closest to the hyperplane

• B.

Furthest from the hyperplane

• C.

Class centroids

• D.

Equally distributed

A. Closest to the hyperplane
Explanation
The SVM decision boundary is determined by the data points that are closest to the hyperplane, known as support vectors.

### SVM is considered a binary classification algorithm, but it can be extended to handle multiple classes using:

• A.

One-vs-One approach

• B.

One-vs-All approach

• C.

Multi-class kernels

• D.

Multi-dimensional scaling

A. One-vs-One approach
Explanation
SVM is considered a binary classification algorithm, but it can be extended to handle multiple classes using the One-vs-One approach. This approach builds multiple binary classifiers for each pair of classes.
