[Algorithm][Parametric] Emerging Convolutions

[jejjohnson]

Probably the only implementation that allows for invertible convolutions which spatial awareness. It is related to the autoregressive method so it will be fast for density estimates but slow for sampling.

  They create the exponential convolution transform. It basically uses the exponential of the convolutions. It approximates the transform via a Taylor series. It generalizes most of the householder approaches, i.e. Sylvester Flows.
