VENUS 2

Description

---

Venus is a complete verification tool for Relu-based feed-forward neural networks. Venus implements a MILP-based verification method whereby it leverages dependency relations between the ReLU nodes to reduce the search space that needs to be considered during branch-and-bound. The dependency relations are exploited via callback cuts and via a branching method that divides the verification problem into a set of sub-problems whose MILP formulations require fewer integrality constraints.

Requirements

---

• Python 3.7 or higher
• Gurobi 9.1 or higher.
