Let's talk about linear regression, a fundamental supervised machine learning technique used for modeling the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data for prediction and analysis. We'll cover types, assumptions, implementation details like cost functions and gradient descent, evaluation metrics, regularization techniques, a Python implementation, and applications across various fields, along with its advantages and disadvantages. We will then look at a more formal statistical perspective, detailing the formulation, extensions to more complex models, various estimation methods beyond least squares, applications in diverse domains, and its historical context. Together, this video is a comprehensive overview of linear regression from practical implementation to theoretical underpinnings and real-world usage. Hosted on Acast.
