- D . read
HOTSPOT
For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.
Explanation:
You train a regression model by using unlabeled data.
No, this is false. Regression models are supervised learning models that require labeled data for training. Unlabeled data doesn’t have the outcome variable needed for regression training.
The classification technique is used to predict sequential numerical data over time.
No, this is false. Classification is used for categorizing inputs into two or more classes, not for predicting numerical data over time. Time series forecasting or regression techniques are more suitable for predicting numerical data over time.
Grouping items by their common characteristics is an example of clustering.
Yes, this is true. Clustering is an unsupervised learning technique where you group data points that have similar characteristics.
