CutMix is a data augmentation technique that addresses the issue of information lossand inefficiency present in regional dropout strategies.Instead of removing pixels and filling them with black or grey pixels or Gaussian noise,you replace the removed regions with a patch from another image,while the … See more The CutMix function takes two image and label pairs to perform the augmentation. It samples λ(l) from the Beta distribution and returns a bounding box from get_box function. We then … See more In this example, we trained our model for 15 epochs.In our experiment, the model with CutMix achieves a better accuracy on the CIFAR-10 dataset(80.36% in our experiment) … See more Webstill gained few insights. We learned that complex data augmentations, especially the ones with higher dimensionality of perturbations (CutMix Sprinkles), lead to improved generalization. During our research we were also able to get better understanding of how each hyper-parameter of augmentation inﬂuences the training results.
