Derive the dual form of svm with hard margin

Webframework based on the support vector machine (SVM) [4]. The key of the framework is to embed an infinite number of hypotheses into an SVM kernel. Such a framework can be applied both to construct new kernels, and to interpret some existing ones [6]. Furthermore, the framework allows a fair comparison between SVM and ensemble learning algorithms. WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts.
