Akopọ

An augmentation must preserve the target label or explicitly adjust it to match the transformed example.

Jin Dive

Augmentation expands the training distribution through transformations or combinations. Mixup creates convex combinations of examples and labels. CutMix replaces a patch and mixes labels in proportion to area. AutoAugment searches for policies using validation performance, while back-translation creates synthetic paraphrases for text tasks. The methods are task-specific: transformations that preserve labels for one task may invalidate labels for another.

Ojo iwaju ti Data Augmentation

Select augmentations based on task semantics and validate on data representative of deployment. Record transformation distributions and test for synthetic artifacts or label mismatch. The cited papers report specific datasets and experiments, not a guarantee that more augmentation always improves generalization.

Real-World imuse

Random crops or flips can create altered image views when the label remains valid.

Mixup linearly combines two inputs and their labels.

CutMix pastes an image region from one example into another and weights labels by area.

Back-translation generates paraphrased text by translating through an intermediate language.

What is Data Augmentation?

Data augmentation transforms or combines training examples to improve learning from available data. An augmentation must preserve the target label or explicitly adjust it to match the transformed example.
