Webb13 apr. 2024 · We can easily fit linear regression models quickly and make predictions using them. A linear regression model is about finding the equation of a line that generalizes the dataset. Thus, we only need to find the line's intercept and slope. The regr_slope and regr_intercept functions help us with this task. http://www.sthda.com/english/articles/40-regression-analysis/165-linear-regression-essentials-in-r/

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. WebbThe first step is to determine which elements to merge in a cluster. Usually, we want to take the two closest elements, according to the chosen distance. Optionally, one can also construct a distance matrix at this stage, where the number in the i -th row j -th column is the distance between the i -th and j -th elements.
