Types of Machine Learning Quiz

What is supervised machine learning?

• Training models using data with known labels

• Training models using only label values

• Training models using data without known labels

• Training models using only feature values

What type of machine learning is regression?

• Unsupervised machine learning

• Supervised machine learning

• Reinforcement learning

• Semi-supervised machine learning

In binary classification, what does the label determine?

• The weight of the observed item

• Whether the observed item is an instance of a specific class

• The size of the observed item

• The color of the observed item

What is the main form of unsupervised machine learning?

• Binary classification

• Clustering

• Regression

• Classification

What does a clustering algorithm identify?

• Similarities between observations based on their features

• Differences between observations based on their features

• Similarities between observations based on their labels

• Differences between observations based on their labels

What is the label predicted by regression models?

• A numeric value

• A true/false prediction

• A categorization

• A binary outcome

What does multiclass classification extend from?

• Unsupervised machine learning

• Binary classification

• Regression

• Clustering

What is the purpose of multilabel classification models?

• To predict more than one valid label for a single observation

• To predict a single valid label for a single observation

• To predict a binary outcome for a single observation

• To predict a numeric value for a single observation

What is the difference between clustering and classification?

• Classification has no previously known cluster label

• Classification uses known cluster labels

• Clustering has no previously known cluster label

• Clustering uses known classification labels

What is the most common form of unsupervised machine learning?

• Classification
