对复杂、病态、非线性动态系统进行故障预报的重点和难点是建立系统故障状况的数学模型,通常难以建立精确的数学模型,相比之下构建其模糊模型是一个有效途径.本文研究了相关向量机(Relevancevectormachine,RVM)与模糊推理系统(Fuzzyinferencesystem,FIS)之间的内在联系,证明了基于RVM的FIS具有一致逼近性,并提出了一种基于RVM和梯度下降(Gradientdescent,GD)算法的模糊模型辨识方法.基于所给出的模糊模型辨识方法提出了一种新的故障预报算法.仿真结果表明所建立的模糊模型不仅结构更加简单,而且能达到更高的预测精度,所提出的故障预报算法能准确地预报系统故障.

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
