All Implemented Interfaces:

DActivationSigmoid<deepboof.tensors.Tensor_F64>, deepboof.DFunction<deepboof.tensors.Tensor_F64>, deepboof.forward.ActivationSigmoid<deepboof.tensors.Tensor_F64>, deepboof.Function<deepboof.tensors.Tensor_F64>

public class DActivationSigmoid_F64
extends ElementWiseDFunction<deepboof.tensors.Tensor_F64>
implements DActivationSigmoid<deepboof.tensors.Tensor_F64>

Implementation of DActivationSigmoid for Tensor_F64. Saves the sigmoid computed on the forward pass to avoid recomputing the sigmoid on the backwards pass.
