SAITS: Self-Attention-based Imputation for Time Series [PDF]

open access: yesExpert systems with applications, 2022
Missing data in time series is a pervasive problem that puts obstacles in the way of advanced analysis. A popular solution is imputation, where the fundamental challenge is to determine what values should be filled in.

Diffusion-based Time Series Imputation and Forecasting with Structured State Space Models [PDF]

open access: yesTrans. Mach. Learn. Res., 2022
The imputation of missing values represents a significant obstacle for many real-world data analysis pipelines. Here, we focus on time series data and put forward SSSD, an imputation model that relies on two emerging technologies, (conditional) diffusion

PriSTI: A Conditional Diffusion Framework for Spatiotemporal Imputation [PDF]

open access: yesIEEE International Conference on Data Engineering, 2023
Spatiotemporal data mining plays an important role in air quality monitoring, crowd flow modeling, and climate forecasting. However, the originally collected spatiotemporal data in real-world scenarios is usually incomplete due to sensor failures or ...

MissForest - non-parametric missing value imputation for mixed-type data [PDF]

open access: yesBioinform., 2011
MOTIVATION Modern data acquisition based on high-throughput technology is often facing the problem of missing data. Algorithms commonly used in the analysis of such large-scale data often depend on a complete set.

Evaluating the Accuracy of Imputation Methods in a Five-Way Admixed Population

open access: yesFrontiers in Genetics, 2019
Genotype imputation is a powerful tool for increasing statistical power in an association analysis. Meta-analysis of multiple study datasets also requires a substantial overlap of SNPs for a successful association analysis, which can be achieved by ...
