Data Augmentation
A regularization technique in deep learning that artificially expands the diversity of a training set by applying random transformations—such as flipping, rotation, cropping, and color jitter—to training samples. Its purpose is to improve model generalization and reduce overfitting.
Timeline (last 90 days)
Common methods in academia and industry for addressing few-shot defect detection include anomaly detection (such as autoencoder reconstruction error methods), data augmentation and synthetic defect generation, transfer learning, and semi-supervised/self-supervised learning.
Methods to mitigate overfitting and improve generalization include data augmentation (rotation, cropping, brightness adjustment), regularization, Dropout, and introducing more real-world samples.
A study systematically compared two categories of data augmentation approaches across four low-resource languages plus English and five different data scales, with analysis carried down to the phoneme level.
Unconstrained graph models trained with randomly rotated samples can reduce coordinate dependence but cannot eliminate it entirely.
Certain data augmentation techniques (such as random noise and blurring) may have a negative impact on specific tasks and need to be manually assessed and removed.
Multimedia content such as images and videos cannot be meaningfully augmented, leading to a natural scarcity of violating samples and difficulties with model cold-start.
YOLO training integrates data augmentation techniques such as Mosaic augmentation, MixUp, and HSV color space perturbation by default.
