Dimensionality Reduction

The process of reducing the number of random variables under consideration in a dataset.

Description

Dimensionality reduction is the process of reducing the number of features in a dataset while retaining as much information as possible. It's used to simplify datasets, reduce computational complexity, and mitigate the curse of dimensionality.

Examples

  • 🧮 Principal Component Analysis (PCA)
  • 🗺️ t-SNE
  • 🧠 Autoencoders

Applications

🗜️ Data compression
🧹 Noise reduction
📊 Visualization of high-dimensional data
