LiDAR–camera fusion for road detection using a recurrent conditional random field model [PDF]
Scientific Reports, 2022 Reliable road detection is an essential task in autonomous driving systems. Two categories of sensors are commonly used, cameras and light detection and ranging (LiDAR), each of which can provide corresponding supplements.

Spherical Model in a Random Field [PDF]
Journal of Statistical Physics, 2007 We investigate the properties of the Gibbs states and thermodynamic observables of the spherical model in a random field. We show that on the low-temperature critical line the magnetization of the model is not a self-averaging observable, but it self ...

Dynamical Properties of Random Field Ising Model [PDF]
Physical Review E, 2013 Extensive Monte Carlo simulations are performed on a two-dimensional random field Ising model. The purpose of the present work is to study the disorder-induced changes in the properties of disordered spin systems. The time evolution of the domain growth,

Random field model reveals structure of the protein recombinational landscape. [PDF]
PLoS Computational Biology, 2012 We are interested in how intragenic recombination contributes to the evolution of proteins and how this mechanism complements and enhances the diversity generated by random mutation.

A Deep-Structured Conditional Random Field Model for Object Silhouette Tracking. [PDF]
PLoS ONE, 2015 In this work, we introduce a deep-structured conditional random field (DS-CRF) model for the purpose of state-based object silhouette tracking. The proposed DS-CRF model consists of a series of state layers, where each state layer spatially characterizes

Compensated Row-Column Ultrasound Imaging System Using Fisher Tippett Multilayered Conditional Random Field Model. [PDF]
PLoS ONE, 2015 3-D ultrasound imaging offers unique opportunities in the field of non destructive testing that cannot be easily found in A-mode and B-mode images. To acquire a 3-D ultrasound image without a mechanically moving transducer, a 2-D array can be used.

Service-Oriented Node Scheduling Scheme for Wireless Sensor Networks Using Markov Random Field Model [PDF]
Sensors, 2014 Future wireless sensor networks are expected to provide various sensing services and energy efficiency is one of the most important criterions. The node scheduling strategy aims to increase network lifetime by selecting a set of sensor nodes to provide

Statistical inference of selection and divergence from a time-dependent Poisson random field model. [PDF]
PLoS ONE, 2012 We apply a recently developed time-dependent Poisson random field model to aligned DNA sequences from two related biological species to estimate selection coefficients and divergence time.

Random-energy model in random fields [PDF]
Physical Review E, 2006 The random-energy model is studied in the presence of random fields. The problem is solved exactly both in the microcanonical ensemble, without recourse to the replica method, and in the canonical ensemble using the replica formalism. The phase diagrams for bimodal and Gaussian random fields are investigated in detail. In contrast to the Gaussian case,
