FMRI Data Augmentation Via Synthesis [PDF]
2019 IEEE 16th International Symposium on Biomedical Imaging (ISBI 2019), 2019 We present an empirical evaluation of fMRI data augmentation via synthesis. For synthesis we use generative mod-els trained on real neuroimaging data to produce novel task-dependent functional brain images. Analyzed generative mod-els include classic approaches such as the Gaussian mixture model (GMM), and modern implicit generative models such as the ...

Implicit Semantic Data Augmentation for Hand Pose Estimation
IEEE Access, 2022 Data augmentation is a well-known technique used for improving the generalization performance of modern neural networks. After the success of several traditional random data augmentation for images (including flipping, translation, or rotation), a recent

, 2020 We propose a novel data augmentation method `GridMask' in this paper. It utilizes information removal to achieve state-of-the-art results in a variety of computer vision tasks. We analyze the requirement of information dropping. Then we show limitation of existing information dropping algorithms and propose our structured method, which is simple and ...

Empirical copula-based data augmentation for mixed-type datasets: a robust approach for synthetic data generation [PDF]
PeerJ Computer ScienceData augmentation is a critical technique for enhancing model performance in scenarios with limited, sparse, or imbalanced datasets. While existing methods often focus on homogeneous data types (e.g., continuous-only or categorical-only), real-world ...

Gaussian noise up-sampling is better suited than SMOTE and ADASYN for clinical decision making
BioData Mining, 2021 Clinical data sets have very special properties and suffer from many caveats in machine learning. They typically show a high-class imbalance, have a small number of samples and a large number of parameters, and have missing values.
