What is unsupervised learning?
A type of machine learning where algorithms find patterns in data without explicit supervision or labeled examples.
A type of machine learning where algorithms make predictions based on labeled data.
A type of machine learning where algorithms find patterns in data using a reward-based system.
A type of machine learning where algorithms focus on classification tasks.
Which type of learning uses labeled data - supervised or unsupervised?
Unsupervised learning
Supervised learning
What is the main goal of clustering in unsupervised learning?
To reduce the dimensionality of the dataset.
To classify data points into predefined categories.
To group similar data points together based on their features or characteristics.
To make predictions on new data points.
What are outliers in a dataset?
Data points that differ significantly from the rest.
Data points with missing values.
Data points with identical features.
Data points with the highest frequency of occurrence.
What does dimensionality reduction mean?
Increasing the number of features in a dataset.
Removing outliers from a dataset.
Finding the most important feature in the dataset.
Reducing the number of features while keeping important information.
