human augmentation

Q.4 Working on computer vision problems require huge amount of image data. However, when we  have insufficient data, we use image augmentation to create more images from the existing images.Which of the following methods can be used to perform image augmentation?1. Image rotation2. Change colours of the image3. Change contrast and brightness4. All of the above

What is the purpose of data augmentation in deep learning? Question 14Answera.  Reducing the learning rate during trainingb.Expanding the training dataset by applying various transformations to the existing datac. Increasing the complexity of the modeld. Adding noise to the data for regularization
