Learning Continuous Occupancy Maps with the Ising Process Model
Nicholas O'Dell, Christopher Renton, Adrian Wills
We present a new method of learning a continuous occupancy field for use in robot navigation. Occupancy grid maps, or variants of, are possibly the most widely used and accepted me…
Deep kernel learning for integral measurements
Carl Jidling, Johannes Hendriks, Thomas B. Schön +1
Deep kernel learning refers to a Gaussian process that incorporates neural networks to improve the modelling of complex functions. We present a method that makes this approach feas…
Stochastic quasi-Newton with line-search regularization
Adrian Wills, Thomas Schön
In this paper we present a novel quasi-Newton algorithm for use in stochastic optimisation. Quasi-Newton methods have had an enormous impact on deterministic optimisation problems…
Neutron Diffraction Strain Tomography: Demonstration and Proof-of-Concept
A. W. T. Gregg, J. N. Hendriks, C. M. Wensrich +2
Recently, a number of reconstruction algorithms have been presented for residual strain tomography from Bragg-edge neutron transmission measurements. In this paper, we examine whet…
Tomographic Reconstruction of Triaxial Strain Fields from Bragg-Edge Neutron Imaging
J. N. Hendriks, A. W. T. Gregg, R. R. Jackson +6
This paper presents a proof-of-concept demonstration of triaxial strain tomography from Bragg-edge neutron imaging within a three-dimensional sample. Bragg-edge neutron transmissio…
Neutron Transmission Strain Tomography for Non-Constant Stress-Free Lattice Spacing
J. N. Hendriks, C. Jidling, T. B. Schön +3
Recently, several algorithms for strain tomography from energy-resolved neutron transmission measurements have been proposed. These methods assume that the stress-free lattice spac…
A Bayesian Approach to Triaxial Strain Tomography from High-energy X-ray Diffraction
J. N. Hendriks, C. M. Wensrich, A. Wills
Diffraction of high-energy X-rays produced at synchrotron sources can provide rapid strain measurements, with high spatial resolution, and good penetrating power. With an uncollima…
