Keynote talk description:
Kernel methods are a powerful class of algorithms in machine learning that allow linear models to solve non-linear problems. The core idea revolves around the "kernel trick," which enables algorithms to operate in a high-dimensional, implicit feature space without ever explicitly computing the coordinates of the data in that space. Support Vector Machines (SVMs) are a prime example of algorithms that heavily rely on kernel methods, utilizing various kernel functions like polynomial, radial basis function (RBF), or sigmoid kernels to tackle diverse classification and regression tasks. In kernel methods, optimizing kernel parameters is crucial for achieving optimal model performance. Our presentation details novel quantum-based methodologies for the optimization of kernel parameters. These approaches facilitate the attainment of enhanced performance metrics, surpassing the capabilities of conventional classical optimization techniques.
