We will train the model on our training data and then evaluate how well the model performs on data it has never seen - the test set.

In Machine Learning (ML), classification is a supervised learning concept that groups data into classes. Classification usually refers to any kind of problem where a specific type of class label is the result to be predicted from the given input field of data. Some types of classification tasks are:Hyperplane Equation: f (x)= sign(w ⋅x+b) f ( x) = sign ( w ⋅ x + b) Goal: Minimize the complexity of the line while correctly classifying points. Soft Margin SVM: Allows for some errors when the data isn't perfectly separable.
