Optbayesexpt:自适应测量的序列贝叶斯实验设计
Optbayesexpt是一个公共领域的开源python包,它为模型函数中的参数的有效估计/测量提供了自适应算法。参数估计是一种测量类型,通常通过一系列数据采集步骤然后进行ftting来处理。该软件旨在提供基于数据的实验控制,有效地从传入的测量结果中学习,并使用这些信息在测量过程中实时和在线选择未来的测量设置。所选择的设置具有改善测量结果的最佳机会。通过这些方法,optbayesexpt旨在提高测量序列的效率,从而产生更好的结果和/或更低的成本。在最近的一项实验中,optbayesexpt在宽光谱范围内测量几个窄峰的速度提高了一个数量级[1]。图1展示了一个可能的使用场景,其中仪器控制程序与python服务器脚本中的optbayesexpt函数进行交互。服务器脚本在后台运行,两个程序通过TCP套接字进行通信。对于N个测量中的每一个,控制器程序提示服务器脚本基于参数概率分布推荐高效用设置。然后,控制器进行测量并将新数据报告回服务器脚本,服务器脚本使用贝叶斯推理来重新定义参数分布,以便在下一次迭代中使用。

期刊介绍: The Journal of Research of the National Institute of Standards and Technology is the flagship publication of the National Institute of Standards and Technology. It has been published under various titles and forms since 1904, with its roots as Scientific Papers issued as the Bulletin of the Bureau of Standards. In 1928, the Scientific Papers were combined with Technologic Papers, which reported results of investigations of material and methods of testing. This new publication was titled the Bureau of Standards Journal of Research. The Journal of Research of NIST reports NIST research and development in metrology and related fields of physical science, engineering, applied mathematics, statistics, biotechnology, information technology.
