Question & Answer
Choose the Best Answer
They reduce data complexity by maximizing variance along new axes.
They create complex feature interactions that increase dimensionality.
They serve to classify data points into predefined categories.
They ensure that all data dimensions contribute equally to the output.
Understanding the Answer
Let's break down why this is correct
Eigenvectors point to directions where the data spreads the most. Other options are incorrect because Some think eigenvectors add more features, but they actually pick the best ones; Eigenvectors are not used to label data.
