Input Convex Neural Networks Offer Optimization Gains Over FNNs

Researchers have introduced Input Convex Neural Networks (ICNNs) as a superior alternative to traditional Feedforward Neural Networks (FNNs) for use in mathematical optimization problems. ICNNs offer computational advantages due to their convex architecture, leading to tighter linear programming relaxations and potentially eliminating integrality gaps. While FNNs with ReLU activations can be reformulated as mixed-integer programming problems, ICNNs allow for an LP-based reformulation via epigraph representations. Case studies in areas like humanitarian food aid, oil well routing, and wine blending demonstrate that ICNNs match FNN accuracy while improving solve times and scalability, making them a strong choice for convex or near-convex functions.
