Adversarial Robustness in Deep Learning: Attacks on Fragile Neurons
Chandresh Pravin, Ivan Martino, Giuseppe Nicosia +1
We identify fragile and robust neurons of deep learning architectures using nodal dropouts of the first convolutional layer. Using an adversarial targeting algorithm, we correlate…
Cooperative games on simplicial complexes
Ivan Martino
In this work, we define cooperative games on simplicial complexes, generalizing the study of probabilistic values of Weber and quasi-probabilistic values of Bilbao, Driessen, Jimén…
Efficiency Axioms for simplicial complexes
Ivan Martino
We study the notion of efficiency for cooperative games on simplicial complexes. In such games, the grand coalition may be forbidden, and, thus, it is a non-trivial problem t…
Probabilistic values for simplicial complexes
Ivan Martino
In this manuscript, we define and study probabilistic values for cooperative games on simplicial complexes. Inspired by the work of Weber "Probabilistic values for games", we estab…
Set of independencies and Tutte polynomial of matroids over a domain
Alessio Borzì, Ivan Martino
In this work, we study matroids over a domain and several classical combinatorial and algebraic invariants related. We define their Grothendieck-Tutte polynomial $T_{\mathcal{M}}(x…
On the codimension of Noether-Lefshetz loci for toric threefolds
Valeriano Lanza, Ivan Martino
In this manuscript we sharpen the lower bound on the codimension of the irreducible components of the Noether-Lefschetz locus of surfaces in projective toric threefolds given in [B…
