Biosignal Data Augmentation Based On Generative Adversarial Networks

Research Paper on Biosignal Data Augmentation Based On Generative Adversarial Networks

Research Area:  Machine Learning


In this paper, we propose a synthetic generation method for time-series data based on generative adversarial networks (GANs) and apply it to data augmentation for biosignal classification. GANs are a recently proposed framework for learning a generative model, where two neural networks, one generating synthetic data and the other discriminating synthetic and real data, are trained while competing with each other. In the proposed method, each neural network in GANs is developed based on a recurrent neural network using long short-term memories, thereby allowing the adaptation of the GANs framework to time-series data generation. In the experiments, we confirmed the capability of the proposed method for generating synthetic biosignals using the electrocardiogram and electroencephalogram datasets. We also showed the effectiveness of the proposed method for data augmentation in the biosignal classification problem.
