Kernel extreme learning machine based on fuzzy set theory for multi-label classification

Abstract

Multi-label classification is a special kind of classification problem, where a single instance can be labeled to more than one class. Extreme learning machine (ELM) with kernel is an efficient method for solving both regression and multi-class classification problems. However, ELM with kernel has a limitation when it comes to multi-label classification tasks. To solve this problem, this paper proposes an enhanced ELM with kernel based on a fuzzy set theory for multi-label classification problems. The relationship between an instance and its corresponding class can be defined as the fuzzy membership. This fuzzy membership is used in output weights computation to weigh the training sample towards the corresponding classes. The experimental results demonstrate that the proposed method outperforms the ELM family of algorithms for multi-label problems, as well as the state-of-the-art multi-label classification algorithms.
