Estimation of Self-Exciting Point Processes from Time-Censored Data
Thomas Alois Weber, Philipp Schneider
Self-exciting point processes, widely used to model arrival phenomena in nature and society, are often difficult to identify. The estimation becomes even more challenging when arrivals are recorded only as bin counts on a finite partition of the observatio ...
2023Analysis-aware defeaturing of complex geometries
Pablo Antolin Sanchez, Ondine Gabrielle Chanon
Local modifications of a computational domain are often performed in order to simplify the meshing process and to reduce computational costs and memory requirements. However, removing geometrical features of a domain often introduces a non-negligible error ...
2022Recursive evaluation and iterative contraction of N-body equivariant features
Michele Ceriotti, Sergey Pozdnyakov, Jigyasa Nigam
Mapping an atomistic configuration to a symmetrized N-point correlation of a field associated with the atomic positions (e.g., an atomic density) has emerged as an elegant and effective solution to represent structures as the input of machine-learning algo ...
