Hadamard Walsh space based hybrid technique for image data augmentation [PDF]
Image data augmentation (IDA) is common when deep learning is used for image classification to address the issue of overfitting. Overfitting occurs when the datasets are small and the deep learning models have a huge capacity. Overfitting models have low
