Linear regression is an algorithm that finds a linear relationship between a dependent variable and one or more independent variables. The dependent variable is also called label and independent variables are called features as well.
Linear regression is one of the most foundational algorithms for statistical and machine learning analysis.
PyTorch is an open source machine learning framework introduced by Facebook in 2016. PyTorch is based on the Torch library, and it’s a Python-based framework as well. Apart from its Python interface, PyTorch also has a C++ front end.
