【神经网络】Reducing the Dimensionality of Data with Neural Networks

用神经网络来降维、之前降维用的方法是主成分分析法PCA，找到数据集中最大方差方向。（附：降维有助于分类、可视化、交流和高维信号的存储）这篇paper提出了一种非线性的PCA 的推广，通过一个小的中间层来重构高维输入向量，训练一个多层神经网...

【Deep Learning】Hinton. Reducing the Dimensionality of Data with Neural Networks Reading Note

　　2006年，机器学习泰斗、多伦多大学计算机系教授GeofferyHinton在Science发表文章，提出基于深度信念网络（DeepBeliefNetworks,DBN）可使用非监督的逐层贪心训练算法，为训练深度神经网络带来了希望。如果说Hinton2006年发表在《Science》杂志上的论文[1]只是在学术界掀...
