Dimensionality Reduction Techniques: PCA and t-SNE Explained Meta Description Explore the fundamentals of dimensionality reduction with a focus on Principal Component Analysis (PCA) and t-Distributed Stochastic Neighbor Embedding (t-SNE), two powerful techniques for simplifying high-dimensional data. Introduction In the era of big data, dealing with high-dimensional datasets is commonplace. While these datasets can provide valuable insights, they often pose challenges in terms of computation, visualization, and analysis. Dimensionality reduction techniques are essential tools that simplify complex data by reducing the number of features while preserving significant patterns and structures. This article delves into two widely used dimensionality reduction methods: Principal Component Analysis (PCA) and t-Distributed Stochastic Neighbor Embedding (t-SNE) . What Is Dimensionality Reduction? Dimensionality reduction involves transforming data from a high-dimensional space into a lo...
