How does the curse of dimensionality relate to feature selection?

  • It can cause overfitting
  • It can make visualizing data difficult
  • It increases computational complexity
  • It reduces the effectiveness of distance-based methods
The curse of dimensionality refers to the various problems that arise when dealing with high-dimensional data. In the context of feature selection, high dimensionality can reduce the effectiveness of distance-based methods, as distances in high-dimensional space become less meaningful.
