Centroidal Voronoi Tessellation Based Methods for Optimal Rain Gauge Location Prediction
Zichao Wendy Di, Viviana Maggioni, Yiwen Mei +3
With more satellite and model precipitation data becoming available, new analytical methods are needed that can take advantage of emerging data patterns to make well informed predi…
Bilevel Optimization, Deep Learning and Fractional Laplacian Regularization with Applications in Tomography
Harbir Antil, Zichao Di, Ratna Khatri
In this work we consider a generalized bilevel optimization framework for solving inverse problems. We introduce fractional Laplacian as a regularizer to improve the reconstruction…
Simultaneous Sensing Error Recovery and Tomographic Inversion Using an Optimization-based Approach
Anthony P. Austin, Zichao Wendy Di, Sven Leyffer +1
Tomography can be used to reveal internal properties of a 3D object using any penetrating wave. Advanced tomographic imaging techniques, however, are vulnerable to both systematic…
