Time Series Generation with Masked Autoencoder

Mengyue Zha, SiuTim Wong, Mengqi Liu +2

This paper shows that masked autoencoder with extrapolator (ExtraMAE) is a scalable self-supervised model for time series generation. ExtraMAE randomly masks some patches of the or…

Combining case-control studies for identifiability and efficiency improvement in logistic regression

Wenlu Tang, Yuanyuan Lin, Linlin Dai +1

Can two separate case-control studies, one about Hepatitis disease and the other about Fibrosis, for example, be combined together? It would be hugely beneficial if two or more sep…

Broken Adaptive Ridge Regression for Right-Censored Survival Data

Zhihua Sun, Yi Liu, Kani Chen +1

Broken adaptive ridge (BAR) is a computationally scalable surrogate to -penalized regression, which involves iteratively performing reweighted penalized regressions and…
