matlab-kalman
说明: 卡尔曼滤波的一个典型实例是从一组有限的,对物体位置的,包含噪声的观察序列预测出物体的坐标位置及速度. 在很多工程应用(雷达, 计算机视觉)中都可以找到它的身影. 同时,卡尔曼滤波也是控制理论以及控制系统工程中的一个重要话题.
比如,在雷达中,人们感兴趣的是跟踪目标,但目标的位置,速度,加速度的测量值往往在任何时候都有噪声.卡尔曼滤波利用目标的动态信息,设法去掉噪声的影响,得到一个关于目标位置的好的估计。这个估计可以是对当前目标位置的估计(滤波),也可以是对于将来位置的估计(预测),也可以是对过去位置的估计(插值或平滑).

gradient descent
说明: 梯度下降法是一個一階最佳化算法,通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值,必須向函數上當前點對應梯度(或者是近似梯度)的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索,則會接近函數的局部極大值點;這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)

cic
当前工程上广泛采用了一种高效滤波器,即CIC(cascaded integrator-comb filter)将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)
