MFAI: A Scalable Bayesian Matrix Factorization Approach to Leveraging Auxiliary Information

1 code implementation5 Mar 2023 Zhiwei Wang, Fa Zhang, Cong Zheng, Xianghong Hu, Mingxuan Cai, Can Yang

Here, we consider a matrix factorization problem by utilizing auxiliary information, which is massively available in real-world applications, to overcome the challenges caused by poor data quality.

A Dataset for Learning Graph Representations to Predict Customer Returns in Fashion Retail

no code implementations27 Feb 2023 Jamie McGowan, Elizabeth Guest, Ziyang Yan, Cong Zheng, Neha Patel, Mason Cusack, Charlie Donaldson, Sofie de Cnudde, Gabriel Facini, Fabon Dzogang

We first explore the structure of this dataset with a focus on the application of Graph Representation Learning in order to exploit the natural data structure and provide statistical insights into particular features within the data.

Wiener filters on graphs and distributed polynomial approximation algorithms

no code implementations9 May 2022 Cong Zheng, Cheng Cheng, Qiyu Sun

In this paper, we consider Wiener filters to reconstruct deterministic and (wide-band) stationary graph signals from their observations corrupted by random noises, and we propose distributed algorithms to implement Wiener filters and inverse filters on networks in which agents are equipped with a data processing subsystem for limited data storage and computation power, and with a one-hop communication subsystem for direct data exchange only with their adjacent agents.
