BAMBI: An R package for Fitting Bivariate Angular Mixture Models
Saptarshi Chakraborty, Samuel W. K. Wong
Statistical analyses of directional or angular data have applications in a variety of fields, such as geology, meteorology and bioinformatics. There is substantial literature on de…
An Efficient Algorithm for Matrix-Valued and Vector-Valued Optimal Mass Transport
Yongxin Chen, Eldad Haber, Kaoru Yamamoto +2
We present an efficient algorithm for recent generalizations of optimal mass transport theory to matrix-valued and vector-valued densities. These generalizations lead to several ap…
Learning task structure via sparsity grouped multitask learning
Meghana Kshirsagar, Eunho Yang, Aurélie C. Lozano
Sparse mapping has been a key methodology in many high-dimensional scientific problems. When multiple tasks share the set of relevant features, learning them jointly in a group dra…
Matricial Wasserstein-1 Distance
Yongxin Chen, Tryphon T. Georgiou, Lipeng Ning +1
In this note, we propose an extension of the Wasserstein 1-metric () for matrix probability densities, matrix-valued density measures, and an unbalanced interpretation of mass…
Efficient-robust routing for single commodity network flows
Yongxin Chen, Tryphon T. Georgiou, Michele Pavon +1
We study single commodity network flows with suitable robustness and efficiency specs. An original use of a maximum entropy problem for distributions on the paths of the graph turn…
On the Matrix Monge-Kantorovich Problem
Yongxin Chen, Wilfrid Gangbo, Tryphon T. Georgiou +1
The classical Monge-Kantorovich (MK) problem as originally posed is concerned with how best to move a pile of soil or rubble to an excavation or fill with the least amount of work…
