COMET Flows: Towards Generative Modeling of Multivariate Extremes and Tail Dependence

1 code implementation2 May 2022 Andrew McDonald, Pang-Ning Tan, Lifeng Luo

In particular, existing normalizing flow architectures struggle to model multivariate extremes, characterized by heavy-tailed marginal distributions and asymmetric tail dependence among variables.

Defending Backdoor Data Poisoning Attacks by Using Noisy Label Defense Algorithm

no code implementations29 Sep 2021 Boyang Liu, Zhuangdi Zhu, Pang-Ning Tan, Jiayu Zhou

We first discuss the limitations of directly using the noisy-label defense algorithms to defend against backdoor attacks.

Learning Deep Neural Networks under Agnostic Corrupted Supervision

no code implementations12 Feb 2021 Boyang Liu, Mengying Sun, Ding Wang, Pang-Ning Tan, Jiayu Zhou

Training deep neural models in the presence of corrupted supervision is challenging as the corrupted data points may significantly impact the generalization performance.

Provable Robust Learning under Agnostic Corrupted Supervision

no code implementations1 Jan 2021 Boyang Liu, Mengying Sun, Ding Wang, Pang-Ning Tan, Jiayu Zhou

Training deep neural models in the presence of corrupted supervisions is challenging as the corrupted data points may significantly impact the generalization performance.

Fairness Perception from a Network-Centric Perspective

no code implementations7 Oct 2020 Farzan Masrour, Pang-Ning Tan, Abdol-Hossein Esfahanian

We show how the function can be extended to a group fairness metric known as fairness visibility and demonstrate its relationship to demographic parity.

Spatially Constrained Spectral Clustering Algorithms for Region Delineation

no code implementations21 May 2019 Shuai Yuan, Pang-Ning Tan, Kendra Spence Cheruvelil, Sarah M. Collins, Patricia A. Soranno

To address these two challenges, first, we develop a spatially constrained spectral clustering framework for region delineation that incorporates the tradeoff between region homogeneity and spatial contiguity.

A Low Rank Weighted Graph Convolutional Approach to Weather Prediction

no code implementations IEEE 2018 Tyler Wilson, Pang-Ning Tan, Lifeng Luo

Specifically, our proposed approach uses an LSTM to capture the inherent temporal autocorrelation of the data and a graph convolution to model its spatial relationships.
