Erratum to: One-class kernel subspace ensemble for medical image classification

After publication of our work [1] we noticed that there were three references and an acknowledgment missing. These are given below: Figure 5 and Figure 6 should be referenced with reference number 53 from the reference list in [1]. The first sentence in section 4.1.2 ‘The 3D OCT retinal image set was collected at the Royal Hospital of University of Liverpool’ should be referenced with [2]. The Acknowledgments should also state that ‘The authors appreciate Dr. Yalin Zheng and Mr. Albarrark A. for their support on the 3D OCT retinal image set used in the paper’.
