Despite the significant advancements made by deep models in various visual tasks, their success largely relies on the availability of vast amounts of annotated training data. However, annotating data can be a time-consuming and labor-intensive process, particularly in complex tasks such as object detection. To address this challenge, relaxing the labeling cost has become a critical problem in deep learning. In this talk, I will explore a potential solution to this problem through the view of data augmentation. Specifically, I will introduce "Random Erasing," a simple and effective data augmentation method that generates new visual training samples by randomly erasing regions within images. This method is network-agnostic and can be easily applied to various vision tasks, resulting in consistent performance improvement. This method has been included in PyTorch as a data augmentation function.
