As we continue moving toward mass adoption, directed acyclic graphs certainly show some promise in addressing the nagging issue of scalability.

Tangle is the distributed ledger for the cryptocurrency network IOTA. Instead of a linear block system like a blockchain, it uses a direct acyclic graph architecture.

The PC-algorithm was shown to be a powerful method for estimating the equivalence class of a potentially very high-dimensional acyclic directed graph (DAG) with the corresponding Gaussian distribution ...

Collapsibility means that the same statistical result of interest can be obtained before and after marginalization over some variables. In this paper, we discuss three kinds of collapsibility for ...
