Types of Machine Learning

Supervised Learning Overview

• Supervised learning occurs when an algorithm learns from example data paired with corresponding target responses.
• It is characterized by training models on labeled datasets, allowing the algorithm to make predictions based on prior learned patterns.

Goals of Supervised Learning

• The primary goal is to accurately predict the output variable from input variables by generalizing from the training data.
• It aims to minimize the error between predicted and actual target responses to improve model performance.

Comparison to Human Learning

• Similar to human learning under the guidance of a teacher, supervised learning involves direct instruction through labeled datasets.
• The algorithm is 'taught' using examples where the correct output is known, enhancing its understanding of input-output relationships.

Input and Output Variables

• Input variables (features) are the data attributes used by the algorithm to make predictions.
• The output variable (target) is the result the algorithm is trying to predict based on input variables.

Learning Mapping Functions

• Supervised learning employs algorithms to learn the mapping function that connects input variables to output variables.
• This enables the model to predict outcomes for new, unseen data, leveraging the learned associations from the training set.
