A Mathematical Certification for Positivity Conditions in Neural Networks With Applications to Partial Monotonicity and Trustworthy AI

This research presents LipVor, an algorithm that mathematically verifies whether a trained neural network (a computer model with interconnected nodes that learns patterns) follows partial monotonicity constraints, which means outputs change predictably with certain inputs. The method works by testing the network at specific points and using mathematical properties to guarantee the network behaves correctly across its entire domain, potentially allowing neural networks to be used in critical applications like credit scoring where trustworthiness and predictable behavior are required.
