WebA Linear Transformation, also known as a linear map, is a mapping of a function between two modules that preserves the operations of addition and scalar multiplication. In short, it is the transformation of a function T. U, also called the domain, to the vector space V, also called the codomain. ( T : U → V ) The linear transformation has two ... In this article, we talked about linear separability.We also showed how to make the data linearly separable by mapping to another feature space. Finally, we introduced kernels, which allow us to fit linear models to non-linear data without transforming the data, opening a possibility to map to even infinite … See more In this tutorial, we’ll explain linearly separable data. We’ll also talk about the kernel trick we use to deal with the data sets that don’t exhibit … See more The concept of separability applies to binary classificationproblems. In them, we have two classes: one positive and the other negative. We say they’re separable if there’s a classifier whose decision boundary separates … See more Let’s go back to Equation (1) for a moment. Its key ingredient is the inner-product term . It turns out that the analytical solutions to fitting linear models include the inner products of the instances in the dataset. When … See more In such cases, there’s a way to make data linearly separable. The idea is to map the objects from the original feature space in which the classes aren’t linearly separable to a new one in which they are. See more
