Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Unsupervised learning algorithms are used for tasks like data summarization and exploratory data analysis. Reason R: Unsupervised learning requires labelled dataset to find relationships and patterns in data. In the light of the above statements, choose the most appropriate answer from the options given below
Analysis of Assertion A and Reason R
Assertion A: Unsupervised learning algorithms are used for tasks like data summarization and exploratory data analysis.
- Unsupervised learning works with data that does not have predefined labels or target outputs.
- Common applications include finding hidden patterns, grouping similar data points (clustering), reducing the number of variables (dimensionality reduction), and gaining insights through data summarization and exploratory data analysis.
- Therefore, Assertion A is correct.
Reason R: Unsupervised learning requires labelled dataset to find relationships and patterns in data.
- This statement describes supervised learning, which uses labeled datasets to train models.
- Unsupervised learning, by definition, operates on *unlabeled* data. It aims to discover inherent structures or patterns within the data itself without prior knowledge of the correct output.
- Therefore, Reason R is incorrect.
Conclusion
Since Assertion A is correct and Reason R is incorrect, the most appropriate answer is that A is correct but R is not correct.
