直接上代码： C语言：#include <stdio.h>#include <algorithm>void mean(float *data,int len,float &mean,float &max,float &min){ float sum=data[0]; max=data[0]; min=data[...

摘要本文将介绍一种常用的神经网络—循环神经网络(recurrent neural network,RNN)以及循环神经网络的一个重要的变体—长短时记忆网络(long short-term memory,LSTM).循环神经网络简介循环神经网络的主要用途是处理和预测序列数据.传统的卷积神经网络(CNN)或者全连接神经网络(FC)都是从输入层到隐含层再到输出层,层与层之间是全连接或部分...

From Logistic Regression with a Neural Network mindset, we achieved the Neural Network which use Logistic Regression to resolve the linear classification . In this blog ,we will achieve a Neural Netwo...

General Architecture of the learning algorithmIt’s time to design a simple algorithm to distinguish cat images from non-cat images.I will build a Logistic Regression, using a Neural Network mindset....

A common technique we use in Machine Learning and Deep Learning is to normalize our data. It often leads to a better performance because gradient descent converges faster after normalization. Here, by...
