Linear Algebra in Data Science
- (Stanford University - Jaclyn Chen)
- Overview
Linear algebra (LA) is considered the most important math skill in machine learning. Most machine learning models can be expressed as matrices, and datasets are often represented as matrices.
Linear algebra can also help with understanding statistics. Statistics are important for machine learning to effectively organize and integrate data.
Linear algebra provides tools and techniques for representing and manipulating data in AI. AI algorithms use linear algebraic operations to handle and examine large amounts of data.
Linear Algebra in data science offers essential tools for interacting with data in numerous approaches, understanding relationships between variables, performing dimensionality reduction, and solving systems of equations. Linear algebra techniques, including matrix operations and eigenvalue decomposition, are typically used for tasks like regression, clustering, and machine learning algorithms.
To excel in data science, it’s essential to have a strong grasp of linear algebra because it underpins many of the mathematical and computational techniques used to analyze and extract insights from data. Additionally, various programming libraries, such as NumPy (Python) and MATLAB, provide tools for performing these linear algebra operations efficiently.
