# Reducing the Dimensionality of Data with Neural Networks

@article{Hinton2006ReducingTD, title={Reducing the Dimensionality of Data with Neural Networks}, author={Geoffrey E. Hinton and Ruslan Salakhutdinov}, journal={Science}, year={2006}, volume={313}, pages={504 - 507} }

High-dimensional data can be converted to low-dimensional codes by training a multilayer neural network with a small central layer to reconstruct high-dimensional input vectors. Gradient descent can be used for fine-tuning the weights in such “autoencoder” networks, but this works well only if the initial weights are close to a good solution. We describe an effective way of initializing the weights that allows deep autoencoder networks to learn low-dimensional codes that work much better than…
