分类视角下的复值与实值神经网络:非循环数据示例
Complex-Valued vs. Real-Valued Neural Networks for Classification Perspectives: An Example on Non-Circular Data
摘要:
本文的贡献是双重的。首先,我们展示了复值神经网络(CVNN)对复值数据集分类任务的潜在兴趣。为了突出这一论断,我们研究了一个复值数据的例子,其中实部和虚部通过非圆特性在统计上是相关的。在这种情况下,完全连接的前馈CVNN的性能进行比较,对一个实值等效模型。结果表明,CVNN表现更好的各种体系结构和数据结构。与实值神经网络(RVNN)相比,CVNN的准确性在统计学上具有更高的平均值和中位数以及更低的方差。此外,如果不使用正则化技术,CVNN表现出较低的过拟合。第二个贡献是使用Tensorflow作为后端发布了一个Python库(Barrachina 2019),该库支持CVNN的实现和训练,希望能够激励对该领域的进一步研究。
英文摘要:
The contributions of this paper are twofold. First, we show the potential interest of Complex-Valued Neural Network (CVNN) on classification tasks for complex-valued datasets. To highlight this assertion, we investigate an example of complex-valued data in which the real and imaginary parts are statistically dependent through the property of non-circularity. In this context, the performance of fully connected feed-forward CVNNs is compared against a real-valued equivalent model. The results show that CVNN performs better for a wide variety of architectures and data structures. CVNN accuracy presents a statistically higher mean and median and lower variance than Real-Valued Neural Network (RVNN). Furthermore, if no regularization technique is used, CVNN exhibits lower overfitting. The second contribution is the release of a Python library (Barrachina 2019) using Tensorflow as back-end that enables the implementation and training of CVNNs in the hopes of motivating further research on this area.
