Latent ODEs for Irregularly-Sampled Time Series

Yulia Rubanova, Ricky T. Q. Chen, D. Duvenaud•Sun Jul 07 2019

This work generalizes RNNs to have continuous-time hidden dynamics defined by ordinary differential equations (ODEs), a model they are called ODE-RNNs, which outperform their RNN-based counterparts on irregularly-sampled data.

GAIN: Missing Data Imputation using Generative Adversarial Nets

M. Schaar, Jinsung Yoon, James Jordon•Wed Jun 06 2018

This work proposes a novel method for imputing missing data by adapting the well-known Generative Adversarial Nets (GAN) framework and calls it GAIN, which significantly outperforms state-of-the-art imputation methods.

Recurrent Neural Networks for Multivariate Time Series with Missing Values

Kyunghyun Cho, D. Sontag, Yan Liu, Zhengping Che, S. Purushotham•Sun Jun 05 2016

Novel deep learning models are developed based on Gated Recurrent Unit, a state-of-the-art recurrent neural network that takes two representations of missing patterns, i.e., masking and time interval, and effectively incorporates them into a deep model architecture so that it not only captures the long-term temporal dependencies in time series, but also utilizes the missing patterns to achieve better prediction results.

ANODE: Unconditionally Accurate Memory-Efficient Gradients for Neural ODEs

A. Gholami, K. Keutzer, G. Biros•Tue Feb 26 2019

ANODE is proposed, an Adjoint based Neural ODE framework which avoids the numerical instability related problems, and provides unconditionally accurate gradients, and discusses a memory efficient algorithm which can further reduce this footprint with a trade-off of additional computational cost.

Neural Ordinary Differential Equations

Yulia Rubanova, D. Duvenaud, T. Chen, J. Bettencourt•Mon Jun 18 2018

This work shows how to scalably backpropagate through any ODE solver, without access to its internal operations, which allows end-to-end training of ODEs within larger models.

Estimating Missing Data in Temporal Data Streams Using Multi-Directional Recurrent Neural Networks

Jinsung Yoon, W. Zame, M. van der Schaar•Wed Nov 22 2017

This work proposes a new approach, based on a novel deep learning architecture that is called a Multi-directional Recurrent Neural Network that interpolates within data streams and imputes across data streams that provides dramatically improved estimation of missing measurements.

GP-VAE: Deep Probabilistic Time Series Imputation

S. Mandt, Vincent Fortuin, Dmitry Baranchuk, Gunnar Rätsch•Sun Jun 30 2019

This work proposes a new deep sequential latent variable model for dimensionality reduction and data imputation of multivariate time series from the domains of computer vision and healthcare, and demonstrates that this approach outperforms several classical and deep learning-based data imputations methods on high-dimensional data.

Deep Learning for Multivariate Time Series Imputation: A Survey

Yuxuan Liang, Wenjie Du, Jun Wang, Wei Cao, Keli Zhang, Wenjia Wang, Qingsong Wen•Mon Feb 05 2024

This survey provides a comprehensive summary of deep learning approaches for multivariate time series imputation (MTSI) tasks and proposes a novel taxonomy that categorizes existing methods based on two key perspectives: imputation uncertainty and neural network architecture.
