摘要
本文报告了我们的初步研究,旨在检验人工神经网络训练方法在土地覆盖分类中的有效性。我们考虑了三种训练方法,即梯度下降法、共轭梯度法和拟牛顿法。我们应用这些方法从覆盖城市地区的Landsat Enhanced Thematic Mapper Plus (ETM+)场景中获得土地覆盖信息。我们的初步实验结果表明,训练方法可以影响神经网络在土地覆盖分类精度方面的整体效率。
A preliminary study of three training methods for land cover classification by artificial neural networks
This paper reports our preliminary study that aims to examine the effectiveness of training methods for land cover classification by artificial neural networks. We consider three training methods, namely, the gradient descent method, the conjugate gradient method, and the Quasi-Newton method. We apply these methods to derive land cover information from a Landsat Enhanced Thematic Mapper Plus (ETM+) scene covering a urban area. Our initial experiment results suggest training methods can affect the overall efficiency of neural networks in terms of land cover classification accuracy.
