A Data-Augmentation Is Worth A Thousand Samples: Exact Quantification From Analytical Augmented Sample Moments

open access: yes, 2022
Data-Augmentation (DA) is known to improve performance across tasks and datasets. We propose a method to theoretically analyze the effect of DA and study questions such as: how many augmented samples are needed to correctly estimate the information encoded by that DA? How does the augmentation policy impact the final parameters of a model?

Spatial-temporal data-augmentation-based functional brain network analysis for brain disorders identification

open access: yesFrontiers in Neuroscience, 2023
IntroductionDue to the lack of devices and the difficulty of gathering patients, the small sample size is one of the most challenging problems in functional brain network (FBN) analysis.

Dynamic Data Augmentation Method for Hyperspectral Image Classification Based on Siamese Structure

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
At present, deep learning classification researches of hyperspectral usually focus on optimizing the classification model. In essence, most of them did not take special measures for the characteristics of the small sample and imbalanced category ...

MetaAugment: Sample-Aware Data Augmentation Policy Learning

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
Automated data augmentation has shown superior performance in image recognition. Existing works search for dataset-level augmentation policies without considering individual sample variations, which are likely to be sub-optimal. On the other hand, learning different policies for different samples naively could greatly increase the computing cost.

Augmenting source code lines with sample variable values [PDF]

open access: yesProceedings of the 26th Conference on Program Comprehension, 2018
Source code is inherently abstract, which makes it difficult to understand. Activities such as debugging can reveal concrete runtime details, including the values of variables. However, they require that a developer explicitly requests these data for a specific execution moment.

Variational Autoencoders for Data Augmentation in Clinical Studies

open access: yesApplied Sciences, 2023
Sample size estimation is critical in clinical trials. A sample of adequate size can provide insights into a given population, but the collection of substantial amounts of data is costly and time-intensive.
