After reading the Andrew Ng‘ s deep learing videos, I try to make a logistic regression model all by myself. This models is very easy in machine learning, and i made it with python. But i failed made it , because i get a bad predict rate and i don’t know why. After that i r...
Python regression neural network Python回归神经网络:实现预测模型 引言 神经网络是一种强大的机器学习算法,可用于解决回归问题。回归问题是指预测连续数值的问题,如房价预测、股票价格预测等。本文将介绍如何使用Python构建一个基本的回归神经网络模型,并进行简单的预测。 神经网络简介 神经网络由多个神经元组成,每个神经...
当用一般的Neural Network做影像处理时,需要用到太多的参数: CNN减少参数主要考虑三个方面的性质: 1、可连接图片中更小的有效区域: 2、当一些相同的模式出现在图片的不同区域时,可采用相同的参数集合来处理:... [Python]自动、使用镜像网站自动和手动安装Numpy [Python]自动、使用镜像网站自动和手动安装Numpy 直接...
前面几层由交替的卷积层和最大池化层组成。然而,后面几层是全连接(fully-connected)层,相当于一个传统的MLP(隐层(hidden layer)+逻辑回归(logistic regression))。第一个全连接层的输入是前一层所有特征图的集合。 从应用的角度出发,这意味着前面几层是以四维张量进行操作。然后这些四维张量被整理成栅格状特征图...
This article assumes you have at least intermediate-level programming skills, but doesn’t assume you know much about neural network regression. The demo program is coded using C#, but you shouldn’t have very much trouble refactoring the code to another language such as Visual Basic or Perl....
