Hi, I am using FullyConnectedNetworkRegressor to build an ML pipeline. The FullyConnectedNetworkConfiguration allows one to specify hiddenUnitCounts for the hidden layers, but I don't see any way to specify or get the activation function for the hidden layers. Is there a way to specify the activation function for the hidden layers? If not, does anyone know what activation function is used for the hidden layers or how they are determined? Thanks, Tom
