Understanding Machine Learning-CR

Which type of system cannot improve without new human-written rules?

• Data-Driven System

• Supervised Learning

• Rule-Based System

• Reinforcement Learning

Which best describes a data-driven system?

• Learns patterns from examples

• Always follows fixed instructions

• Predicts without using data

• Only works for numbers

A teacher gives students both the questions and answers while practicing. This is most like:

• Unsupervised Learning

• Supervised Learning

• Reinforcement Learning

• Rule-Based System

Predicting house prices based on size and location is an example of:

• Classification

• Regression

• Clustering

• Reinforcement

Which of these tasks would most likely use clustering?

• Sorting fruits into 'ripe' or 'not ripe'

• Predicting next week's rainfall in millimeters

• Grouping customers by spending habits

• Teaching a robot to walk across a room

Which type of learning is most similar to trial and error?

• Supervised

• Unsupervised

• Reinforcement

• Rule-Based

A mobile app suggests friends to follow by analyzing who you interact with, without labels. This is an example of:

• Supervised Learning

• Reinforcement Learning

• Rule-Based System

• Unsupervised Learning

Which system is the least flexible when conditions change?

• Rule-Based

• Supervised ML

• Unsupervised ML

• Reinforcement Learning
