hdMTD: An R Package for High-Dimensional Mixture Transition Distribution Models
Maiara Gripp, Giulio Iacobelli, Guilherme Ost +1
Several natural phenomena exhibit long-range conditional dependencies. High-order mixture transition distribution (MTD) are parsimonious non-parametric models to study these phenom…
Community detection for binary graphical models in high dimension
Julien Chevallier, Guilherme Ost
Let components be partitioned into two communities, denoted and , possibly of different sizes. Assume that they are connected via a directed and weight…
Self-switching random walks on Erdös-Rényi random graphs feel the phase transition
Giulio Iacobelli, Guilherme Ost, Daniel Y. Takahashi
We study random walks on Erdös-Rényi random graphs in which, every time the random walk returns to the starting point, first an edge probability is independently sampled according…
Self-Switching Markov Chains: emerging dominance phenomena
S. Gallo, G. Iacobelli, G. Ost +1
In many dynamical systems in nature, the law of the dynamics changes along with the temporal evolution of the system. These changes are often associated with the occurrence of cert…
