The ReLU Type option determines the specific ReLU activation functions that can be used with the DPUCZDX8G. ReLU and ReLU6 are supported by default. Selection of the option “ReLU + LeakyReLU + ReLU6“ will enable LeakyReLU as an activation function.

Note: For this implementation, the LeakyReLU coefficient is fixed to 0.1 which is approximated as 26/256 = 0.1015625
