Multi Scale Flows

• The first partition z1 is processed by a series of reversible layers with the same dimension as z1 until, at some point, z2 is appended and combined with the first partition.
• This continues until the network is the same size as the data x.
• In the normalizing direction, the network starts at the full dimension of x, but when it reaches the point where zn was added, this is assessed against the base distribution
