nnf_sigmoid

Applies element-wise \(Sigmoid(x_i) = \frac{1}{1 + exp(-x_i)}\)

Provides functionality to define and train neural networks similar to
'PyTorch' by Paszke et al (2019) <arXiv:1912.01703> but written entirely in R
using the 'libtorch' library. Also supports low-level tensor operations and
'GPU' acceleration.
