Abstract

Due to the popularity of artificial intelligent, medical image processing using artificial neural network is increasingly attracting the attention of academic and industry researches. Deep learning with a convolutional neural network has been proved to very effective representation of images. However, the training process requires high performance H/W platform. Thus, the realtime learning of a large number of high dimensional samples within low-power devices is a challenging problem. In this paper, we attempt to establish this possibility by presenting a realtime neural network method on Raspberry pi using online sequential extreme learning machine. Our experiments on high-dimensional dataset show that the proposed method records an almost real-time execution.

최근 인공지능에 대중의 관심으로 인해, 인공신경망을 사용한 의료영상 처리가 학계와 산업계에서 관심이 커져가고 있다. 딥러닝을 이용한 컨볼루션 신경망은 영상을 효과적으로 표현할 수 있는 것으로 증명되었다. 그러나 학습을 위해서는 고성능 H/W 플랫폼이 요구된다. 따라서 고차원의 많은 학습 샘플을 저사양 H/W 플랫폼에서 학습하는 것은 매우 도전적인 문제이다. 본 논문에서는 온라인 인공 신경망을 사용해 라즈베리파이에서 동작할 수 있는 실시간 신경망 알고리즘을 제안하고자 한다. 다양한 실험 결과를 통해 제안된 방법은 실시간 학습이 가능함을 보여주었다.
