Continuous-time Autoencoders for Regular and Irregular Time Series Imputation

no code implementations27 Dec 2023 Hyowon Wi, Yehjin Shin, Noseong Park

However, it has been overlooked for a long time to design an imputation method based on continuous-time recurrent neural networks (RNNs), i. e., neural controlled differential equations (NCDEs).

Graph Convolutions Enrich the Self-Attention in Transformers!

no code implementations7 Dec 2023 Jeongwhan Choi, Hyowon Wi, Jayoung Kim, Yehjin Shin, Kookjin Lee, Nathaniel Trask, Noseong Park

We propose a graph-filter-based self-attention (GFSA) to learn a general yet effective one, whose complexity, however, is slightly larger than that of the original self-attention mechanism.
