Title: Self-Pretraining for Small Datasets by Exploiting Patch Information. Abstract:   Deep learning tasks with small datasets are often tackled by pretraining models with large datasets on relevent tasks. Although pretraining methods mitigate the problem of overfitting, it can be difficult to find appropriate pretrained models sometimes. In this paper, we proposed a self-pretraininng method by exploiting patch information in the dataset itself without pretraining on other datasets. Our experiments show that the self-pretraining method leads to better performance than training from scratch both in the condition of not using other data.
