How can dimensionality reduction be helpful in visualizing data?

  • By increasing model accuracy
  • By reducing data to 2D or 3D
  • By reducing noise
  • By reducing overfitting
Dimensionality reduction can be used to reduce data to 2D or 3D, making it possible to visualize the data in plots or graphs. Visualization helps in understanding underlying patterns and structures in the data but is unrelated to model accuracy, overfitting, or noise reduction.
