- It is the first to propose a new generative model structure called Expansion Flow, or EFlow, which increases dimensionality during generation.
- It alternates expand and transport operations to generate high-quality samples in only one or two steps.
- For molecular graph generation, it reduces the one-step FCD error to 0.44 versus 2.14 for the prior CFM method.
- It also outperforms fixed-length models on language generation, which shows that variable-length generation does not hurt quality.
- It demonstrates that the same framework works in both continuous domains, such as molecular structure, and discrete domains, such as graphs and language.
