为此,本文提出了利用遗传算法[3]优化BP神经网络模拟损伤识别,利用遗传算法对BP神经网络的权值和阈值进行优化[4],提高神经网络的收敛速度和泛化能力,从而获得更好的识别效果.本文以Benchmark模型[5]为研究对象,验证该方法的可行性,如图1所示。 1 Benchmark模型损伤识别 Benchmark是一個四层钢框架结构,横纵各两跨,...

例如，在金融新闻中，"100 basis point increase in the bank reserve ratio requirement"意味着商业银行的存款准备金率上调了100个基点；"27 basis point reduction in its benchmark rate"表示基准利率下调了27个基点。在债券市场中，"basis point"用于衡量收益率的变化，如"yield on 10-year government...
BENCHMARK: Browne faces challenge to keep BP at the topEDITED by RICHARD WACHMAN
3thefacedetectiondataset&benchmark(fdd-b) 4cmudataset(cmu) 图4中,将本发明方法的平均检测时间和经典bp神经算法在上述4种数据中检测人脸的平均时间做了一个比较。 因为afw和cmu两个数据集中的每张图像中会具有多个人脸和较为复杂的图像背景,所以在这两个数据集上的检测时性能改善更为明显。
