Parameterized Complexity of -Lipschitz Constants for Input Convex Neural Networks and -Norm Maximization over Zonotopes
Aritra Das, Vincent Froese, Moritz Grillo +6
Lipschitz constants are a standard way to quantify the sensitivity of neural networks to small input perturbations, but computing them is difficult even for shallow ReLU networks.…
Tropical Circuits with Scalar Multiplication Gates
Christoph Hertrich, Moritz Stargalla
We study tropical circuits with scalar multiplication gates, that is, algebraic circuits whose gates implement , , or multiplication with a positive constant. For such cir…
Parameterized Hardness of Zonotope Containment and Neural Network Verification
Vincent Froese, Moritz Grillo, Christoph Hertrich +1
Neural networks with ReLU activations are a widely used model in machine learning. It is thus important to have a profound understanding of the properties of the functions computed…
The Computational Complexity of Counting Linear Regions in ReLU Neural Networks
Moritz Stargalla, Christoph Hertrich, Daniel Reichman
An established measure of the expressive power of a given ReLU neural network is the number of linear regions into which it partitions the input space. There exist many different,…
