摘要:

许多研究已经调查了在现实世界中应用的合成数据的神经网络的训练。本研究的目的是量化在使用合成数据集和真实世界数据的混合数据集时可以节省多少真实世界数据。通过一个简单的幂律模型的训练样本的数量和检测性能之间的关系,我们发现,对真实世界的数据可以减少高达70%,而不牺牲检测性能。目标检测网络的训练特别是通过用在现实世界数据集中代表性不足的类来丰富混合数据集来增强。结果表明,真实世界数据比率在5%到20%之间的混合数据集在不降低检测性能的情况下最大限度地减少了对真实世界数据的需求。

英文摘要:

A number of studies have investigated the training of neural networks with synthetic data for applications in the real world. The aim of this study is to quantify how much real world data can be saved when using a mixed dataset of synthetic and real world data. By modeling the relationship between the number of training examples and detection performance by a simple power law, we find that the need for real world data can be reduced by up to 70% without sacrificing detection performance. The training of object detection networks is especially enhanced by enriching the mixed dataset with classes underrepresented in the real world dataset. The results indicate that mixed datasets with real world data ratios between 5% and 20% reduce the need for real world data the most without reducing the detection performance.
