IVGAE: Handling Incomplete Heterogeneous Data with a Variational Graph Autoencoder
Youran Zhou, Mohamed Reda Bouadjenek, Sunil Aryal%
Handling missing data remains a fundamental challenge in real-world tabular datasets, especially when data are heterogeneous with both numerical and categorical features. Existing…
MissHDD: Hybrid Deterministic Diffusion for Hetrogeneous Incomplete Data Imputation
Youran Zhou, Mohamed Reda Bouadjenek, Sunil Aryal
Incomplete data are common in real-world tabular applications, where numerical, categorical, and discrete attributes coexist within a single dataset. This heterogeneous structure p…
MissMecha: An All-in-One Python Package for Studying Missing Data Mechanisms
Youran Zhou, Mohamed Reda Bouadjenek, Sunil Aryal
Incomplete data is a persistent challenge in real-world datasets, often governed by complex and unobservable missing mechanisms. Simulating missingness has become a standard approa…
MissDDIM: Deterministic and Efficient Conditional Diffusion for Tabular Data Imputation
Youran Zhou, Mohamed Reda Bouadjenek, Sunil Aryal
Diffusion models have recently emerged as powerful tools for missing data imputation by modeling the joint distribution of observed and unobserved variables. However, existing meth…
Handling Out-of-Distribution Data: A Survey
Lakpa Tamang, Mohamed Reda Bouadjenek, Richard Dazeley +1
In the field of Machine Learning (ML) and data-driven applications, one of the significant challenge is the change in data distribution between the training and deployment stages,…
Far From Sight, Far From Mind: Inverse Distance Weighting for Graph Federated Recommendation
Aymen Rayane Khouas, Mohamed Reda Bouadjenek, Hakim Hacid +1
Graph federated recommendation systems offer a privacy-preserving alternative to traditional centralized recommendation architectures, which often raise concerns about data securit…
