The Estimator class, just like the Transformer class, was introduced in Spark 1.3. The Estimators, as the name suggests, estimate the parameters of a model or, in other words, fit the models to data.
In this recipe, we will introduce two models: the linear SVM acting as a classification model, and a linear regression model predicting the forest elevation.
Here is a list of all of the Estimators, or machine learning models, available in the ML module:
LinearSVC is an SVM model for linearly separable problems. The SVM's kernel has the
form (a hyperplane), where is the coefficients (or a normal vector ...
