What is the process of categorizing data into predefined classes based on input features using a machine learning algorithm?

• A. Classification
• B. Data
• C. Preprocessing
• D. Tool creation

Answer: (A)

Classification is the process of categorizing data into predefined classes based on input features. In supervised learning, a model learns from labeled examples to map feature patterns to a discrete category, producing a label from a fixed set rather than a continuous value. This is what enables tasks like deciding whether an email is spam or not, or labeling an image as a dog or a cat. The other terms refer to different parts of working with data: data is the raw material itself, preprocessing involves cleaning and transforming data before modeling, and tool creation isn’t a standard ML task. So classification is the best fit here.
