Biomedical data acquisition, and reaching sufficient samples of participants are difficult and time ans effort consuming processes. On the other hand, the success rates of computer aided diagnosis (CAD) algorithms are sample and feature space depended. In this paper, conditional generative adversarial network (CGAN) based enhanced feature generation is proposed to synthesize large sample datasets having higher class separability. Twenty five percent of five medical datasets are used to train CGAN, and the synthetic datasets with any sample size are evaluated and compared to originals. Thus, new datasets can be generated with the help of the CGAN model and lower sample collection. It helps physicians decreasing sample collection processes, and it increases accuracy rates of the CAD systems using generated enhanced data with enhanced feature vectors. The synthesized datasets are classified using nearest neighbor, radial basis function support vector machine and artificial neural network to analyze the effectiveness of the proposed CGAN model.
生物医学数据采集以及获取足够数量的参与者样本是困难且耗时费力的过程。另一方面,计算机辅助诊断(CAD)算法的成功率取决于样本和特征空间。本文提出基于条件生成对抗网络(CGAN)的增强特征生成方法,以合成具有更高类可分性的大样本数据集。五个医学数据集中的25%用于训练CGAN,并对任意样本大小的合成数据集进行评估并与原始数据集进行比较。因此,借助CGAN模型可以生成新的数据集并减少样本采集。这有助于医生减少样本采集过程,并提高使用生成的具有增强特征向量的增强数据的CAD系统的准确率。使用最近邻、径向基函数支持向量机和人工神经网络对合成数据集进行分类,以分析所提出的CGAN模型的有效性。
