What are some common challenges in high-dimensional data that dimensionality reduction aims to address?

  • All of the above
  • Computational efficiency
  • Curse of dimensionality
  • Overfitting
Dimensionality reduction aims to address several challenges in high-dimensional data, including the curse of dimensionality (where distance measures lose meaning), overfitting (where models fit noise), and computational efficiency (since fewer dimensions require less computing resources).
