Definition: In this task, you are given the abstract of a research paper. Your task is to generate a summary of this abstract. Your summary should not be very short, but it's better if it's not more than 30 words.
Input: In this work we construct flexible joint distributions from low-dimensional conditional semi-implicit distributions. Explicitly defining the structure of the approximation allows to make the variational lower bound tighter, resulting in more accurate inference.

Utilizing the structure of distributions improves semi-implicit variational inference
