AI总结:

本文针对Kepler望远镜数据,提出Siamese架构解决低数据场景下的系外行星分类问题,其准确率达99%,显著优于CNN和ResNet。

摘要:

NASA的Kepler Space Telescope在寻找银河系中系外行星存在的任务中发挥了关键作用。这一搜索得到了计算数据分析的支持,旨在从Kepler望远镜接收到的信号中识别系外行星。本文考虑在Kepler太空望远镜及其扩展任务K2的数据上,利用残差网络对现有系外行星识别工作进行扩展。本文旨在探索深度学习算法如何帮助在一种数据量较少的情况下和另一种数据种类更广泛的情况下对系外行星的存在进行分类。除了基于标准CNN的方法外,我们提出了一种Siamese架构,该架构特别适用于解决低数据场景下的分类问题。CNN和ResNet算法在三类分类中达到了68%的平均准确率,在二类分类中达到了86%的准确率。然而,对于三类和二类分类,Siamese算法均达到了99%的准确率。

英文摘要:

NASA's Kepler Space Telescope has been instrumental in the task of finding the presence of exoplanets in our galaxy. This search has been supported by computational data analysis to identify exoplanets from the signals received by the Kepler telescope. In this paper, we consider building upon some existing work on exoplanet identification using residual networks for the data of the Kepler space telescope and its extended mission K2. This paper aims to explore how deep learning algorithms can help in classifying the presence of exoplanets with less amount of data in one case and a more extensive variety of data in another. In addition to the standard CNN-based method, we propose a Siamese architecture that is particularly useful in addressing classification in a low-data scenario. The CNN and ResNet algorithms achieved an average accuracy of 68% for three classes and 86% for two-class classification. However, for both the three and two classes, the Siamese algorithm achieved 99% accuracy.
