Abstract
Target coding is an indispensable part of supervised learning. Currently, the assumption of the most popular target coding like one-hot (one-of-K) coding is that targets are independent. However, this assumption is limited due to the complex relationship between targets. In this paper, we will explore the effects of kinds of target coding methods on the performance of Extreme Learning Machine Classifiers (ELM-C). Linearly independent coding (e.g., one-of-k coding, Hadamard coding) and linearly dependent coding (e.g., ordinal coding, binary coding) are analyzed and compared. The experimental results on OCR letter dataset show that different target coding will indeed affect the performance of the same classifier.
