SwitchTab: Switched Autoencoders Are Effective Tabular Learners

no code implementations4 Jan 2024 Jing Wu, Suiyao Chen, Qi Zhao, Renat Sergazinov, Chen Li, ShengJie Liu, Chongchao Zhao, Tianpei Xie, Hanqing Guo, Cheng Ji, Daniel Cociorva, Hakan Brunzel

Self-supervised representation learning methods have achieved significant success in computer vision and natural language processing, where data samples exhibit explicit spatial or semantic dependencies.

Semiblind subgraph reconstruction in Gaussian graphical models

no code implementations15 Nov 2017 Tianpei Xie, Sijia Liu, Alfred O. Hero III

Consider a social network where only a few nodes (agents) have meaningful interactions in the sense that the conditional dependency graph over node attribute variables (behaviors) is sparse.

Robust training on approximated minimal-entropy set

no code implementations21 Oct 2016 Tianpei Xie, Nasser. M. Narabadi, Alfred O. Hero

In this paper, we propose a general framework to learn a robust large-margin binary classifier when corrupt measurements, called anomalies, caused by sensor failure might be present in the training set.

In this paper, we propose a general framework to learn a robust large-margin binary classifier when corrupt measurements, called anomalies, caused by sensor failure might be present in the training set.
