This paper addresses the analysis of the problem of combining Infinite Kernel Learning (IKL) approach and Extreme Learning Machine (ELM) structure. ELM represents a novel and promising alternative to Neural Networks, for its simplicity in implementation and high efficiency, especially concerning convergence and generalization performance. A currently underdeveloped topic concerning ELM implementation is given by the optimization process of base kernels: choosing different kernel combinations may lead to very dissimilar performance results. An innovative ELM approach using a combination of multiple kernels has been proposed in Liu et al. As a change of paradigm, we are interested in using an infinite set of base kernels, defining in this way an original ELM based algorithm called Infinite Kernel Extreme Learning Machine (IK-ELM). About that, a novel 3-step algorithm combining IKL and ELM is proposed. Finally, a brief analysis about further possible directions is discussed.

Abstract
This paper addresses the analysis of the problem of combining Infinite Kernel Learning (IKL) approach and Extreme Learning Machine (ELM) structure. ELM represents a novel and promising alternative to Neural Networks, for its simplicity in implementation and high efficiency, especially concerning convergence and generalization performance. A currently underdeveloped topic concerning ELM implementation is given by the optimization process of base kernels: choosing different kernel combinations may lead to very dissimilar performance results. An innovative ELM approach using a combination of multiple kernels has been proposed in Liu et al. As a change of paradigm, we are interested in using an infinite set of base kernels, defining in this way an original ELM based algorithm called Infinite Kernel Extreme Learning Machine (IK-ELM). About that, a novel 3-step algorithm combining IKL and ELM is proposed. Finally, a brief analysis about further possible directions is discussed.File | Dimensione | Formato | |
