Locally weighted linear regression is a general linear regression method, it's also a local regression method. We can know more about local regression by checking its related wiki: https://en.wikipedia.org/wiki/Local_regression

A regression problem is a type of supervised machine learning task where the objective is to predict an unknown, continuous numerical label based on known input features. It is used to answer 'how much?' or 'how many?' questions. The defining characteristic is that the target labels take on arbitrary numerical values, and the goal of the learning algorithm is to produce a model whose predictions closely approximate these actual observed values.

Locally Weighted Linear Regression

Regression models predict a value Y given a set of X variables.
In the regression model $Y \sim X$, we measure the effect of $X$ on $Y$, i.e., we measure the association between changes in values of $X$ and changes in values of $Y$.
Analyzing a regression model is a method used to solve a regression problem.
