Q.20 Which of the following is NOT supervised learning?1. PCA2. Decision Tree3. Linear Regression4. Naive Bayesian
Question
Solution 1
The answer is 1. PCA (Principal Component Analysis). This is because PCA is an unsupervised machine learning algorithm used for dimensionality reduction or to simplify data structures. It does not require a labeled dataset, unlike the other options (Decision Tree, Linear Regression, Naive Bayesian) Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
