Singular Value Decomposition (SVD) is a powerful technique in linear algebra, used to decompose a matrix into three other matrices. It has numerous applications, particularly in data science, such as dimensionality reduction, noise reduction, and data compression. In NumPy, SVD can be performed using the `numpy.linalg.svd()` function. This function returns three matrices: U, Σ (Sigma), and V*, which represent the decomposition of the original matrix. Understanding SVD is crucial for tasks like image processing, where it helps in compressing images without significant loss of quality. By mastering SVD with NumPy, you can tackle complex data analysis challenges more effectively. We'll look at an example to understand how SVD is implemented and interpreted using NumPy.
