Functions are an important building block in Elm. In this lesson we will review stateless functions, function composition, anonymous functions, Currying, and more. Write Pure function: import Htrml exposing (text) main = view "Hello World" view…

背景: MCU:STM32F207 SPI flash: Winbond W25Q16BV OS: RTT V1.1.1 bsp: STM32F20x 1 将spi_core.c,spi_dev.c及spi.h三个文件加入工程 spi_core.c,spi_dev.c这两个文件位于RTT\components\drivers\spi目录下,而spi.h头文件位于RTT\\components\drivers\include\drivers目录下. 可在MKD工程的Drivers组下将上面两个源文…

1. ELM 是什么 ELM的个人理解: 单隐层的前馈人工神经网络,特别之处在于训练权值的算法: 在单隐层的前馈神经网络中,输入层到隐藏层的权值根据某种分布随机赋予,当我们有了输入层到隐藏层的权值之后,可以根据最小二乘法得到隐藏层到输出层的权值,这也就是ELM的训练模型过程. 与BP算法不同,BP算法(后向传播算法),输入层到隐藏层的权值,和隐藏层到输出层的权值全部需要迭代求解(梯度下降法) 用一张老图来说明,也就是说上图中的Wi1,Wi2,Wi3 在超限学习机中,是随机的,固定的,不需要迭代求…

Before writing any Elm we need to first install the runtime locally. In this lesson we install the Elm runtime locally and set up a simple application to verify everything is working properly. Install: npm install -g elm elm package install elm packa…
