Given a stream of integers and a window size, calculate the moving average of all integers in the sliding window. For example, MovingAverage m = new MovingAverage(3); m.next(1) = 1 m.next(10) = (1 + 10) / 2 m.next(3) = (1 + 10 + 3) / 3 m.next(5) = (1

一般在保存模型参数的时候,都会保存一份moving average,是取了不同迭代次数模型的移动平均,移动平均后的模型往往在性能上会比最后一次迭代保存的模型要好一些. tensorflow-models项目中tutorials下cifar中相关的代码写的有点问题,在这写下我自己的做法: 1.构建训练模型时,添加如下代码 variable_averages = tf.train.ExponentialMovingAverage(0.999, global_step) variables_avera

Python的Queue模块提供一种适用于多线程编程的FIFO实现.它可用于在生产者(producer)和消费者(consumer)之间线程安全(thread-safe)地传递消息或其它数据,因此多个线程可以共用同一个Queue实例.Queue的大小(元素的个数)可用来限制内存的使用. Basic FIFO Queue Queue类实现了一个基本的先进先出(FIFO)容器,使用put()将元素添加到序列尾端,get()从队列尾部移除元素. LIFO Queue 与标准FIFO实现Queue不同的

原来国外有个源码(TechnicalAnalysisEngine src 1.25)内部对EMA的计算是: var copyInputValues = input.ToList(); for (int i = period; i < copyInputValues.Count; i++) { var resultValue = (copyInputValues[i] - returnValues.Last()) * multiplier + returnValues.Last(); return

1. 用滑动平均估计局部均值 滑动平均(exponential moving average),或者叫做指数加权平均(exponentially weighted moving average),可以用来估计变量的局部均值,使得变量的更新与一段时间内的历史取值有关. 变量$v$在$t$时刻记为$v_t$,$\theta_t$为变量$v$在$t$时刻的取值,即在不使用滑动平均模型时$v_t = \theta_t$,在使用滑动平均模型后,$v_t$的更新公式如下: \begin{equation}

问题描述 python 3.0启用日志, 在pycharm里打开.log文件时中文都显示乱码. 根本原因 默认日志编译用的是GBK, 而python 3.0写程序用的是UTF-8. 所以.log文件中文会出现乱码. 解决方法 在日志handle中指定编码表 def log(logging_type): """ 去掉打印在屏幕上的功能 :param logging_type: :return: """ # 传日志用例, 生成日志对象 logger

[理论部分] ARIMA包含两部分,自回归AR和移动平均MA: AR:Y(t)-a=b(1){Y(t-1)-a}+u(t)   其中a是y的均值, u(t)是均值为零,恒定方差的不相关随机误差项(噪声)此公式为一阶自回归AR(1)随机过程.同理可以推广出P阶自回归过程. MA:Y(t)=u+c(0)u(t)+c(1)u(t-1)    其中u是常数项 u(t)是噪声. 此公式为一阶移动平均MA(1)过程.同理可推广出q阶移动平均过程. 如果Y兼具Autoregressive 和 Moving A
