在本論文中,我們先建造了一個基礎模型去檢測光曲線,並且一一去比較卷積神經網絡參數,得到一個最佳模型,然後再利用最佳之模型去比較干擾參數不同的情形下準確率的差別,可發現干擾參數較大準確率較差,因此我們討論干擾參數較大時如何去改善其準確率,並在最後一章做總結。
In this thesis, we first build a basic model to detect the light curve, and compare the Convolutional Neural Network parameters one by one to get an optimal model, and then use this model to compare the difference in accuracy under different parameters. It can be found that the poor accuracy is caused by the large noise, so we discuss how to improve the accuracy when the noise parameter is large. Finally, we make a summary in the last chapter.
