SYNTHETIC DATA AUGMENTATION USING GAN FOR IMPROVED LIVER LESION CLASSIFICATION Maayan Frid-Adar1 Eyal Klang 2Michal Amitai Jacob Goldberger3 Hayit Greenspan1 1Department of Biomedical Engineering, Tel Aviv University, Tel Aviv, Israel. 2.1 Data Augmentation Data augmentation (DA) has become an essential step in training deep learning models, where the goal is to enlarge the training sets to avoid over-fitting. DA has also been explored by the statistical learning community [29, 7] for calculating posterior distributions via the introduction of latent variables. Second, we provide an empirical study on the effectiveness of GAN-based data augmentation for breast cancer classification. Our results indicate that GAN-based augmentation improves mammogram patch-based classification by 0.014 AUC over the baseline model and 0.009 AUC over traditional augmentation techniques alone. (ASC)[26]. In recent work[20, 27], data augmentation for robust speech recognition using GANs was explored at the rst time.

Yet it is expensive to collect data in many domains such as medical applications. 2019-07-06 · This Data Augmentation helped reduce overfitting when training a deep neural network. The authors claim that their augmentations reduced the error rate of the model by over 1%.

The below images shows Data Augmentation Generative Adversarial Network (DAGAN) which is a basic framework based on conditional GAN (cGAN). Researchers tested its effectiveness on vanilla classifiers and one shot. Many face data augmentation researchers followed this architecture and extended it to a more powerful network.

On Data Augmentation for GAN Training. 9 Jun 2020 • Ngoc-Trung Tran • Viet-Hung Tran • Ngoc-Bao Nguyen • Trung-Kien Nguyen • Ngai-Man Cheung. Recent successes in Generative Adversarial Networks (GAN) have affirmed the importance of using more data in GAN training. Yet it is expensive to collect data in many domains such as medical applications. ..

By training a GAN, you're not adding any new information to the dataset, so naturally the GAN cannot produce data from a larger space than the space of the original dataset. It is thus pointless to try to generate new training data with a GAN, because this synthetic data will not contain any new information. $\endgroup$ – Alex Aug 30 '18 at 21:33 Data Augmentation with Conditional GAN for Automatic Modulation Classification WiseML’20, July 13, 2020, Linz (Virtual Event), Austria the training data distribution and function is equal to 0.5.
