WebbThe linear regression model can also be used when the relationship between the variables is non-linear. What is meant here as linearity is that the parameters (beta parameters) … WebbClassification algorithms are supervised learning methods to split data into classes. They can work on Linear Data as well as Nonlinear Data. Logistic Regression can classify data based on weighted parameters and sigmoid conversion to calculate the probability of classes. K-nearest Neighbors (KNN) algorithm uses similar features to classify data.
