What is the curse of dimensionality?

Correct! Well done.

Incorrect.

The correct answer is B) As feature dimensions increase, data becomes increasingly sparse and distances lose meaning, making ML algorithms less effective

B

Correct Answer

As feature dimensions increase, data becomes increasingly sparse and distances lose meaning, making ML algorithms less effective

Explanation

In high dimensions: distances between points converge, volume increases exponentially (more data needed), nearest neighbor becomes unreliable. Dimensionality reduction and feature selection help combat this.
