Convolutional Neural Networks (CNNs) are currently the most advanced machine learning architecture for visual data classification. The choice of activation functions has a significant impact on performance training task. In order to overcome vanishing gradient problem, we propose new function classification system. makes use properties periodic functions, where derivative is also periodic. Furthermore, linear combination introduced prevent from becoming zero. We verify this novel by an...
