Learning About Machine Learning

What is supervised learning?

• Supervised learning is a method that requires no data for training.

• Unsupervised learning uses labeled data to train models.

• Supervised learning is a type of reinforcement learning.

• Supervised learning is a machine learning approach that uses labeled data to train models.

Give an example of unsupervised learning.

• Decision tree

• K-means clustering

• Linear regression

• Support vector machine

What is reinforcement learning?

• Reinforcement learning is a type of machine learning that focuses solely on data analysis.

• Reinforcement learning is a method for supervised learning using labeled data.

• Reinforcement learning is a technique for clustering data points into groups.

• Reinforcement learning is a type of machine learning focused on training agents to make decisions through trial and error to maximize rewards.

Name an application of supervised learning.

• Weather forecasting

• Stock price prediction

• Email spam detection

• Image classification

What is clustering in unsupervised learning?

• Clustering is the process of sorting data points in ascending order.

• Clustering is a method for supervised learning.

• Clustering is the process of grouping similar data points together in unsupervised learning.

• Clustering involves labeling data points with predefined categories.

How do rewards work in reinforcement learning?

• Rewards in reinforcement learning guide the agent's learning process by providing feedback on the effectiveness of its actions.

• Rewards are only given at the end of the learning process.

• Rewards are irrelevant to the agent's actions.

• Rewards are used to punish the agent for mistakes.
