Imputing missing values using cumulative linear regression

open access: yesCAAI Transactions on Intelligence Technology, 2019
The concept of missing data is important to apply statistical methods on the dataset. Statisticians and researchers may end up to an inaccurate illation about the data if the missing data are not handled properly.

Missing the missing values: The ugly duckling of fairness in machine learning

open access: yesInternational Journal of Intelligent Systems, 2021
Nowadays, there is an increasing concern in machine learning about the causes underlying unfair decision making, that is, algorithmic decisions discriminating some groups over others, especially with groups that are defined over protected attributes ...

Large‐scale data visualization with missing values

open access: yesTechnological and Economic Development of Economy, 2006
Visualization of large‐scale data inherently requires dimensionality reduction to 1D, 2D, or 3D space. Autoassociative neural networks with a bottleneck layer are commonly used as a nonlinear dimensionality reduction technique.

A Multilevel Bayesian Approach to Improve Effect Size Estimation in Regression Modeling of Metabolomics Data Utilizing Imputation with Uncertainty

open access: yesMetabolites, 2020
To ensure scientific reproducibility of metabolomics data, alternative statistical methods are needed. A paradigm shift away from the p-value toward an embracement of uncertainty and interval estimation of a metabolite’s true effect size may lead to ...

Energy-based temporal neural networks for imputing missing values [PDF]

open access: yes, 2012
Imputing missing values in high dimensional time series is a difficult problem. There have been some approaches to the problem [11,8] where neural architectures were trained as probabilistic models of the data. However, we argue that this approach is not

Missing Value Imputation With Unsupervised Backpropagation [PDF]

open access: yes, 2013
Many data mining and data analysis techniques operate on dense matrices or complete tables of data. Real-world data sets, however, often contain unknown values.

Analyzing the impact of missing values and selection bias on fairness

open access: yesInternational Journal of Data Science and Analysis, 2021
Algorithmic decision making is becoming more prevalent, increasingly impacting people’s daily lives. Recently, discussions have been emerging about the fairness of decisions made by machines.

Missing values imputation using Fuzzy K-Top Matching Value

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Missing data occurs when variables or observations are missing. Researchers exclude or impute influenced variables and data. This study proposes Fuzzy K-Top Matching Value (FKTM) for missing value imputation.

Dealing with Missing Data using a Selection Algorithm on Rough Sets

open access: yesInternational Journal of Computational Intelligence Systems, 2018
This paper discusses the so-called missing data problem, i.e. the problem of imputing missing values in information systems. A new algorithm, called the ARSI algorithm, is proposed to address the imputation problem of missing values on categorical ...

Adaptive imputation of missing values for incomplete pattern classification [PDF]

open access: yes, 2016
In classification of incomplete pattern, the missing values can either play a crucial role in the class determination, or have only little influence (or eventually none) on the classification results according to the context.
