Here the separating boundary is defined by $\mathring{\mathbf{x}}_{\,}^T\mathbf{w}^{\,}=0$. (right) Nonlinear two-class classification is achieved by injecting nonlinear feature transformations into our model in precisely the same way we did in Section 10.2 with nonlinear regression.

Fabio had three published papers at ESANN (European Symposium on Artificial Neural Networks). The one with most impact is a study that presented concepts of Vector Fields in order to construct a novel type of Neural Network Structure. 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
