Complex Data Imputation by Auto-Encoders and Convolutional Neural Networks—A Case Study on Genome Gap-Filling

Abstract: Missing data imputation has been a hot topic in the past decade, and many state-of-the-art works have been presented to propose novel, interesting solutions that have been applied in a variety of fields. In the past decade, the successful results achieved by deep learning techniques have opened the way to their application for solving difficult problems where human skill is not able to provide a reliable solution. Not surprisingly, some deep learners, mainly exploiting encoder-decoder architectures, have also … Show more

“…Other, more complex techniques, are based on neural networks. Among them, several proposals leverage auto-encoder networks [45] [49] or encoder-decoder Convolutional Neural Networks (CNNs) [50] , [51] in order to reconstruct the training samples in their decoding output. Once trained, such decoding networks are able to reconstruct the missing values in test samples.…”

“…At the state of the art, several imputation models for MCAR methods have been presented that can deal with “complex” data [45] . Among such methods, we experimented both Multiple Imputations by Chained Equations (MICE [23] , [121] ), using either predictive mean matching ( micePMM ) or Random Forest classifiers ( miceRF ) as the base imputation model, and missForest [19] , which also exploits RFs.…”

“…The continuous monitoring of multiple vital signs is crucial for managing critically diseased patients in the intensive care unit (ICU) [1]. Due to the high diversity and volume of data, the resulting databases are highly susceptible to quality issues, such as missing information and errors in data entry [1][2] [3]. Missing data is a common issue in ICU settings due to various factors, such as equipment malfunction, patient movement, or interruptions in data collection [2].…”

“…Due to the promising results achieved by applying Bayesian optimization to complex black box optimizations [ 53 – 55 ], and given its lower computational time when compared to grid search or random search, we have used it for the automatic selection of our classification models, which are described in the following sections.…”
