Singular Value Decomposition (SVD) is a mathematical technique used in linear algebra to factorize a matrix into three other matrices, revealing the intrinsic geometric structure of the data. It is widely used in areas such as signal processing, statistics, and machine learning for dimensionality reduction and noise reduction, among other applications.

Machine learning is a subset of artificial intelligence that involves the use of algorithms and statistical models to enable computers to improve their performance on a task through experience. It leverages data to train models that can make predictions or decisions without being explicitly programmed for specific tasks.

Dimensionality reduction is a process used in data analysis and machine learning to reduce the number of random variables under consideration, by obtaining a set of principal variables. This technique helps in mitigating the curse of dimensionality, improving model performance, and visualizing high-dimensional data in a more comprehensible way.
