Abstract: As a fast iterative neural networks learning algorithm, extreme learning machine (ELM) is a fast learning computation approach, and its whole learning process is completed through a mathematical transformation. However, the number of hidden layer neurons generally requires manual definition. In this paper, we propose an adaptive extreme learning machine (AP-ELM) algorithm which automatically determines the number of hidden layer neurons based on the AP clustering algorithm. In proposed algorithm, the samples are clustered through the AP clustering algorithm and then the number of cluster centres is used to determine the number of hidden layer neurons. Finally, the proposed adaptive ELM algorithm is used to face recognition. Experimental results verify that AP-ELM has good accuracy and reliability.
