Short description explaining what the learner will understand after completing this study map.
Where Machine Learning Is Used
Machine learning can be applied to different kinds of problems. For this topic, focus on recognizing prediction, object recognition, classification, clustering, recommendations, and generative AI.
Application questions are about purpose. Look at what the system is trying to do: predict an outcome, recognize an object, assign a category, discover groups, recommend an item, or generate new content.
Essential Applications

Applications by Task
Different applications can be distinguished by the type of result the machine learning system is expected to produce.
Classification vs Clustering
These two applications are easy to confuse. The key distinction is whether the task assigns known categories or discovers natural groups.
Classification
Assigns an item to a category or class. Example: deciding whether an email belongs to a spam or non-spam category.
Clustering
Groups items according to similarities or patterns. Example: discovering groups of customers with similar behavior.
Choose the Application from the Goal
Read the scenario and identify the intended output. The goal usually points directly to the application type.
Application Examples
Use practical scenarios to connect each application name with its purpose.

Key Takeaways
Use the task being performed—not just the industry or product name—to identify the application.
Prediction estimates an outcome; object recognition identifies objects; classification assigns categories; clustering discovers groups; recommendations suggest relevant items; generative AI creates new content.
Do not confuse classification with clustering. Classification assigns categories, while clustering groups items by similarity.
