Random field optimization [PDF]
Computers & Chemical Engineering, 2022 We present a new modeling paradigm for optimization that we call random field optimization. Random fields are a powerful modeling abstraction that aims to capture the behavior of random variables that live on infinite-dimensional spaces (e.g., space and time) such as stochastic processes (e.g., time series, Gaussian processes, and Markov processes ...

Prediction and classification for finite element slope stability analysis by random field comparison
Computers and Geotechnics, 2019 This paper considers probabilistic slope stability analysis using the Random Finite Element Method (RFEM) combined with processes to determine the level of similarity between random fields.

Random fields and random sampling [PDF]
Kybernetika, 2020 The authors study the limit in distribution of the maximum of a stationary bivariate real random field, sampled at double random times under some dependence conditions. It is shown that the limit distribution is a max-semistable distribution when the random samples have a geometric growth pattern. When the random field is sampled at double random times,

Journal of Civil Engineering and Management, 2023 Probabilistic analysis based on random field (RF) has been widely adopted in the safety assessment of shield tunnels. However, its practical applicability has been limited by the intricacy involved with integrating geotechnical data and tunneling ...

Behavior of Shallow Circular Tunnels—Impact of the Soil Spatial Variability
Geosciences, 2022 Spatial variability is unavoidable for soils and it is important to consider such a feature in the design of geotechnical engineering as it may lead to some structure behaviors which cannot be predicted by a calculation assuming homogenous soils.

BERT has a Mouth, and It Must Speak: BERT as a Markov Random Field Language Model [PDF]
Proceedings of the Workshop on Methods for Optimizing and Evaluating Neural Language Generation, 2019 We show that BERT (Devlin et al., 2018) is a Markov random field language model. This formulation gives way to a natural procedure to sample sentences from BERT.
