Activqtion output, the accuracy and the computational efficiency of a CNN are determined mainly by the architecture, the convolutional filters, and the activation functions.

Based on the importance of an activation function, in this paper, nine new activation definition of causal research design based on combinations of classical functions such as ReLU and sigmoid are presented. Also, a study about the effects caused by the activation functions in the performance of a Ks is presented.
