First-Order Laws for Random Geometric Graphs on the Torus
Simi Haber, Mostafa Mirabi, Saharon Shelah
Let be the random geometric graph generated by independent uniform points on the -dimensional torus, with adjacency defined by torus -distance at most $…
On the most reliable graphs with fixed redundancy
Rotem Brand, Reuven Cohen, Simi Haber +1
The all-terminal reliability of a graph is the probability that remains connected when each edge fails independently with probability . For fixed and , the unifor…
Unsupervised Estimation of Ensemble Accuracy
Simi Haber, Yonatan Wexler
Ensemble learning combines several individual models to obtain a better generalization performance. In this work we present a practical method for estimating the joint power of sev…
Ensemble dependence of the critical behavior of a system with long-range interaction and quenched randomness
Nir Schreiber, Reuven Cohen, Simi Haber
We propose a hybrid model governed by the Blume-Emery-Griffiths (BEG) Hamiltonian with a mean-field-like interaction, where the spins are randomly quenched such that some of them a…
Efficient covering of convex domains by congruent discs
Shai Gul, Reuven Cohen, Simi Haber
In this paper, we consider the problem of covering a plane region with unit discs. We present an improved upper bound and the first nontrivial lower bound on the number of discs ne…
Changeover phenomenon in randomly colored Potts models
Nir Schreiber, Reuven Cohen, Gideon Amir +1
A hybrid Potts model where a random concentration of the spins assume states and a random concentration of the spins assume states is introduced. It is know…
