# Neural Ordinary Differential Equations

Instead of specifying a discrete sequence of hidden layers, we parameterize the derivative of the hidden state using a neural network.

# Latent ODEs for Irregularly-Sampled Time Series

Time series with non-uniform intervals occur in many applications, and are difficult to model using standard recurrent neural networks (RNNs).

# GAIN: Missing Data Imputation using Generative Adversarial Nets

Accordingly, we call our method Generative Adversarial Imputation Nets (GAIN).

# Recurrent Neural Networks for Multivariate Time Series with Missing Values

Multivariate time series data in practical applications, such as health care, geoscience, and biology, are characterized by a variety of missing values.

# ANODE: Unconditionally Accurate Memory-Efficient Gradients for Neural ODEs

ANODE has a memory footprint of O(L) + O(N_t), with the same computational cost as reversing ODE solve.

# BRITS: Bidirectional Recurrent Imputation for Time Series

It is ubiquitous that time series contains many missing values.

# PyPOTS: A Python Toolbox for Data Mining on Partially-Observed Time Series

PyPOTS is an open-source Python library dedicated to data mining and analysis on multivariate partially-observed time series, i. e. incomplete time series with missing values, A. K. A.

# A user-driven case-based reasoning tool for infilling missing values in daily mean river flow records

In this work, we introduce gapIt, a user-driven case-based reasoning tool for infilling gaps in daily mean river flow records.

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

Existing methods address this estimation problem by interpolating within data streams or imputing across data streams (both of which ignore important information) or ignoring the temporal aspect of the data and imposing strong assumptions about the nature of the data-generating process and/or the pattern of missing data (both of which are especially problematic for medical data).

# GP-VAE: Deep Probabilistic Time Series Imputation

Multivariate time series with missing values are common in areas such as healthcare and finance, and have grown in number and complexity over the years.
