Data augmentation is a technique used to increase the diversity of a dataset by applying various transformations to the existing data. This helps improve the generalization and robustness of machine learning models. Here are 100 tips and tricks for data augmentation:

1. Basics of Data Augmentation

1. Understand the importance of data augmentation in preventing overfitting.
2. Apply data augmentation consistently to both the training and validation sets.
3. Experiment with different data augmentation techniques for your specific task.
4. Balance the level of augmentation to avoid generating unrealistic samples.
5. Use data augmentation to simulate variations that the model might encounter in the real world.
6. Implement random transformations to increase the diversity of augmented data.
7. Consider the computational cost of data augmentation, especially for large datasets.
8. Normalize the augmented data to the same scale as the original data.
9. Apply data augmentation in a way that preserves the semantic content of the data.
10. Regularly visualize augmented samples to…
