Inflation Target at Risk: A Time-varying Parameter Distributional Regression

no code implementations19 Mar 2024 Yunyun Wang, Tatsushi Oka, Dan Zhu

Macro variables frequently display time-varying distributions, driven by the dynamic and evolving characteristics of economic, social, and environmental factors that consistently reshape the fundamental patterns and relationships governing these variables.

Distributional Vector Autoregression: Eliciting Macro and Financial Dependence

no code implementations9 Mar 2023 Yunyun Wang, Tatsushi Oka, Dan Zhu

Vector autoregression is an essential tool in empirical macroeconomics and finance for understanding the dynamic interdependencies among multivariate time series.

Towards Adaptive Unknown Authentication for Universal Domain Adaptation by Classifier Paradox

no code implementations10 Jul 2022 Yunyun Wang, Yao Liu, Songcan Chen

In this paper, we propose a new UniDA method with adaptive Unknown Authentication by Classifier Paradox (UACP), considering that samples with paradoxical predictions are probably unknowns belonging to none of the source classes.

Dual-Correction Adaptation Network for Noisy Knowledge Transfer

no code implementations10 Jul 2022 Yunyun Wang, Weiwen Zheng, Songcan Chen

Previous unsupervised domain adaptation (UDA) methods aim to promote target learning via a single-directional knowledge transfer from label-rich source domain to unlabeled target domain, while its reverse adaption from target to source has not jointly been considered yet so far.

Pre-Training on Dynamic Graph Neural Networks

1 code implementation24 Feb 2021 Ke-Jia Chen, Jiajun Zhang, Linpu Jiang, Yunyun Wang, Yuxuan Dai

This paper proposes a pre-training method on dynamic graph neural networks (PT-DGNN), which uses dynamic attributed graph generation tasks to simultaneously learn the structure, semantics, and evolution features of the graph.

Deep Audio Priors Emerge From Harmonic Convolutional Networks

no code implementations ICLR 2020 Zhoutong Zhang, Yunyun Wang, Chuang Gan, Jiajun Wu, Joshua B. Tenenbaum, Antonio Torralba, William T. Freeman

We show that networks using Harmonic Convolution can reliably model audio priors and achieve high performance in unsupervised audio restoration tasks.
