Inverse statistical problems: from the inverse Ising problem to data science
H. Chau Nguyen, Riccardo Zecchina, Johannes Berg
Inverse problems in statistical physics are motivated by the challenges of `big data' in different fields, in particular high-throughput experiments in biology. In inverse problems…
Statistical mechanics of the inverse Ising problem and the optimal objective function
Johannes Berg
The inverse Ising problem seeks to reconstruct the parameters of an Ising Hamiltonian on the basis of spin configurations sampled from the Boltzmann measure. Over the last decade,…
Mean-field theory for the inverse Ising problem at low temperatures
H. Chau Nguyen, Johannes Berg
The large amounts of data from molecular biology and neuroscience have lead to a renewed interest in the inverse Ising problem: how to reconstruct parameters of the Ising model (co…
Bethe-Peierls approximation and the inverse Ising model
H. Chau Nguyen, Johannes Berg
We apply the Bethe-Peierls approximation to the problem of the inverse Ising model and show how the linear response relation leads to a simple method to reconstruct couplings and f…
Spin-models of granular compaction: From one-dimensional models to random graphs
Johannes Berg, Anita Mehta
We discuss two athermal types of dynamics suitable for spin-models designed to model repeated tapping of a granular assembly. These dynamics are applied to a range of models charac…
Metastable configurations of spin models on random graphs
Johannes Berg, Mauro Sellitto
One-flip stable configurations of an Ising-model on a random graph with fluctuating connectivity are examined. In order to perform the quenched average of the number of stable conf…
