Linear neuron: \[y=b+\sum\limits_i{x_i w_i}\] Binary threshold neuron: \[z = \sum\limits_i{x_i w_i}\] \[y=\left\{\begin{aligned} 1,~~~~~~~z\gt \theta \\ 0,otherwise\end{aligned}\right.\] 也可以写作: \[z = \sum\limits_i{x_i w_i}\] \[y=\left\{\begin{aligned…

之前有关卡尔曼滤波的例子都比较简单,只能用于简单的理解卡尔曼滤波的基本步骤.现在让我们来看看卡尔曼滤波在实际中到底能做些什么吧.这里有一个使用卡尔曼滤波在窗口内跟踪鼠标移动的例子,原作者主页:http://home.wlu.edu/~levys/ 首先,第一步是选取状态变量,这里选择系统状态变量为x=[x, y]T ,即状态变量选为鼠标在窗口内的位置.通过鼠标事件响应的回调函数可以获得鼠标当前位置,即观测值z = [x, y]T.对于这一问题外界控制量u=0. 观测噪声和系统噪声的选择需要靠实验…

When a golf player is first learning to play golf, they usually spend most of their time developing a basic swing. Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing. In a…

接下来一段时间开启脉冲神经网络模型的探索之旅.脉冲神经网络有更强的生物学基础,尽可能地模拟生物神经元之间的连接和通信方式.其潜在能力较强,值得踏进一步探索. 构建脉冲神经网络模型,至少需要考虑三点:1. 外界刺激编码2. 构建神经元模型3. 制定学习规则 外界刺激的编码方式主要有Rate Coding和Temporal Coding等,这里不在细述.而Hodgkin和Huxley两位研究员早在1952年就提出了第一个神经元模型:HH[1].随后陆续有各种神经元模型被提出,其中具有代表性的为Izh…
