Question 165:
You work as a machine learning specialist at a mining and minerals company. Your company has asked you to build a model that predicts the efficacy of a given drilling site. Your model training dataset has a large number of features. For your modeling exploration, you have chosen to use regression models, such as linear regression and logistic regression. During exploratory data analysis, you notice a high correlation between many features that you believe will make your model unstable. How can you address the problem of having too many highly correlated features?
Answer options:
A.Use a Cramer’s V correlation coefficient. B.Use Principal Component Analysis to reduce the dimensionality of the dataset. C.Modify highly correlated features using vector multiplication. D.Modify highly correlated features using a Spearman correlation coefficient.
