What is the difference between regression and classification?1 pointMachine learning models can be trained to do regression, but not classification.In regression, the input data is structured, but in classification the input data is unstructured.In regression, the correct answers have numerical value, but in classification the correct answers are categories.Machine learning models can be trained to do classification, but not regression.6.Question 6
Solution
The main difference between regression and classification lies in the type of output they produce and the type of problem they solve.
-
Regression is used to predict a continuous or quantitative output. For example, predicting the temperature for the next week, or the price of a house based on its features. The output here is a numerical value.
-
Classification, on the other hand, is used to predict a categorical or qualitative output. For example, determining whether an email is spam or not, or if a tumor is malignant or benign. The output here is a category.
So, the statement "In regression, the correct answers have numerical value, but in classification the correct answers are categories." is correct.
The other statements are incorrect because:
- Machine learning models can be trained to do both regression and classification, not just one or the other.
- The structure of the input data does not determine whether a problem is a regression or classification problem. Both types of problems can work with structured or unstructured data.
