卷积神经网络(Convolutional Neural Networks, CNN)是一类包含卷积计算且具有深度结构的前馈神经网络(Feedforward Neural Networks),是深度学习(deep learning)的代表算法之一 。卷积神经网络具有表征学习(representation learning)能力,能够按其阶层结构对输入信息进行平移不变分类(shift-invariant classification),因此也被称为...
CNN实验报告 cnn machine learning 什么是深度学习? 机器学习(machine learning):是人工智能的一个分支,致力于研究如何通过计算的手段,利用经验来改善计算机系统自身的性能。凭借机器学习算法来从经验中学习到所需的所有知识,经验:对应以“特征”形式存储的“数据”,传统机器学习算法依靠这些数据产生“模型”。 表示学习(...
在ML里面,听过最多的单词就是卷积神经网络(CNN),CNN是图片识别中比较成功,也比较经典的一种算法。本文就来介绍介绍CNN。CNN 大体上来说分为C和NN,C就是卷积(Convolution),NN 就是神经网络(Neural Network)。所以我们先需要了解一下什么是卷积。 CNN之卷积操作 卷积,这个词不好理解,需要举几个例子来辅助理解。
Overall, CNNs are a powerful and effective deep learning architecture for processing visual data. They have significantly advanced the state of the art in computer vision and image understanding, enabling applications such as facial recognition, object detection, and self-driving cars. With ongoing re...

我个人在玩kaggle和工作中用到最多的主要是树类模型(lgb,xgb)和神经网络(cnn, rnn),确实很少去思考其中的含义和解释性,如果让我自己回答这个问题,我理解到用决策树的信息熵计算统计概率得出叶子节点的重要性,再加上拟合残差的思路就是xgb类的算法了。而神经网络方面,我则简单的理解为求导拟合。高中课本里的一次...
尽管在这一时期,Yann Lecun成功在贝尔实验室训练出了可以准确识别手写数字的卷积神经网络(CNN),但是神经网络没有办法被更大规模的投入实际应用。随着支持向量机(Support Vector Machine)的问世,神经网络再一次被打进冷宫。 用卷积神经网络识别手写数字 深度学习 A Fast Learning Algorithm for Deep Belief Nets, Geoffr...
