Relaxing bijectivity constraints with continuously indexed normalising flows
R Cornish, A Caterini… - … on machine learning, 2020 - proceedings.mlr.press
We show that normalising flows become pathological when used to model targets whose
supports have complicated topologies. In this scenario, we prove that a flow must become …
