______________ is performed without the help of a teacher.

Correct answer is Unsupervised learning.

Key Points

• Unsupervised learning refers to the use of artificial intelligence (AI) algorithms to identify patterns in data sets containing data points that are neither classified nor labeled.
• Unsupervised machine learning finds all kind of unknown patterns in data.
• Unsupervised Learning Algorithms allow users to perform more complex processing tasks compared to supervised learning.
• Unsupervised learning algorithms include clustering, anomaly detection, neural networks, etc.
• Unsupervised learning is performed without the help of a teacher.

Additional Information

• Supervised learning, also known as supervised machine learning, is a subcategory of machine learning and artificial intelligence. 
• Reinforcement learning is the training of machine learning models to make a sequence of decisions.
• Inductive Learning, also known as Concept Learning, is how A.I. systems attempt to use a generalized rule to carry out observations.
