# Which algorithm is used for multi-label classification?

## Which algorithm is used for multi-label classification?

MultinomialNB() is the Naive Bayes algorithm method used for classification. This is important because by converting our multi-label problem to a multi-class problem, we need an algorithm to handle this multi-class problem.

## What is multi-label classification example?

For example, multi-class classification makes the assumption that each sample is assigned to one and only one label: a fruit can be either an apple or a pear but not both at the same time.

Which algorithm is best for multiclass classification?

Popular algorithms that can be used for multi-class classification include:

• k-Nearest Neighbors.
• Decision Trees.
• Naive Bayes.
• Random Forest.

### What is multi-label classification problem?

Multi-label classification involves predicting zero or more class labels. Unlike normal classification tasks where class labels are mutually exclusive, multi-label classification requires specialized machine learning algorithms that support predicting multiple mutually non-exclusive classes or “labels.”

### Which of the following method is used for multiclass classification?

One-vs-rest (OvR for short, also referred to as One-vs-All or OvA) is a heuristic method for using binary classification algorithms for multi-class classification. It involves splitting the multi-class dataset into multiple binary classification problems.

How do you solve multiclass classification?

Approach –

1. Load dataset from the source.
2. Split the dataset into “training” and “test” data.
3. Train Decision tree, SVM, and KNN classifiers on the training data.
4. Use the above classifiers to predict labels for the test data.
5. Measure accuracy and visualize classification.

#### What is multi-label text classification?

Multi-label classification is a generalization of multiclass classification, which is the single-label problem of categorizing instances into precisely one of more than two classes; in the multi-label problem there is no constraint on how many of the classes the instance can be assigned to.”

#### Can SVM be used for multiclass classification?

In its most basic type, SVM doesn’t support multiclass classification. For multiclass classification, the same principle is utilized after breaking down the multi-classification problem into smaller subproblems, all of which are binary classification problems.

Which are the types of multiclass classifier?

Binary Classifiers for Multi-Class Classification

• Logistic Regression.
• Perceptron.
• Support Vector Machines.

## Which are types of multiclass classifier Mcq?

Multiclass classifiers are also known as:

• Mutlilabel classifiers.
• Multinomial classifiers.
• Multioutput classifiers.

What is multi-label multi class classification?

Multilabel classification (closely related to multioutput classification) is a classification task labeling each sample with m labels from n_classes possible classes, where m can be 0 to n_classes inclusive. This can be thought of as predicting properties of a sample that are not mutually exclusive.
