Large Deviations of Convex Hulls of Random Walks and Other Stochastic Models

Hendrik Schawe, Alexander K. Hartmann, Joachim Krug
2019 Zenodo  
The second project examines the distribution of the ground-state energy of a generalized random-energy model, a toy model from statistical physics with applications to phase transitions and spin glasses  ...  There we find a universal asymptotic form for the distribution of the ground-state energies in the limit of large systems, only dependent via two parameters on the behavior of the underlying distribution  ...  Mendonça for useful discussions and his feedback on a draft of the manuscript.

2022 arXiv   pre-print
Besides, we introduce Gravity-Inspired GAE and VGAE, providing the first extensions of these models for directed graphs, that are ubiquitous in industrial applications.  ...  In particular, we show that our methods can improve the detection of communities of similar musical items to recommend to users, that they can effectively rank similar artists in a cold start setting,  ...  Then, we note that A + B is a weakly diagonally dominant matrix (WDD) as, by construction, ∀i ∈ {1, ..., n}, |(A + B) ii | ≥ j =i |(A + B) ij |.  ...

We derive a variety of valid inequalities, and show the role of constraint aggregation and the knapsack problem with generalized upper bound constraints as a way of generating such inequalities.  ...  This allows us to investigate the extent to which conclusions about some aspects of UK economic growth may be rather weakly based. Schepanski, AI Solomou, Solomos Sousa, Jorge P.  ...  AB In this paper we construct a framework for the analysis of the stability of capitalist economies.  ...
