Non-negative Factorization of the Occurrence Tensor from Financial Contracts
Zheng Xu, Furong Huang, Louiqa Raschid +1
We propose an algorithm for the non-negative factorization of an occurrence tensor built from heterogeneous networks. We use l0 norm to model sparse errors over discrete values (oc…
An Empirical Study of ADMM for Nonconvex Problems
Zheng Xu, Soham De, Mario Figueiredo +2
The alternating direction method of multipliers (ADMM) is a common optimization tool for solving constrained and non-differentiable problems. We provide an empirical study of the p…
Training Neural Networks Without Gradients: A Scalable ADMM Approach
Gavin Taylor, Ryan Burmeister, Zheng Xu +3
With the growing importance of large network models and enormous training datasets, GPUs have become increasingly necessary to train neural networks. This is largely because conven…
Adaptive ADMM with Spectral Penalty Parameter Selection
Zheng Xu, Mario A. T. Figueiredo, Tom Goldstein
The alternating direction method of multipliers (ADMM) is a versatile tool for solving a wide range of constrained optimization problems, with differentiable or non-differentiable…
Exploiting Lists of Names for Named Entity Identification of Financial Institutions from Unstructured Documents
Zheng Xu, Douglas Burdick, Louiqa Raschid
There is a wealth of information about financial systems that is embedded in document collections. In this paper, we focus on a specialized text extraction task for this domain. Th…
