Witryna8 sty 2024 · Locally weighted linear regression is a supervised learning algorithm. It is a non-parametric algorithm. There exists No training phase. All the work is done … WitrynaWhen should we use Locally Weighted Regression? Typically, think of linear regression initially as it is the simplest algorithm in all sense. But the issue arises if the linear regression is not fitting well enough or, say that the data follows a non-linear relationship, it will be underfitting and cannot be a reliable model for that case.
