== Overview == Data preprocessing plays a very important in many deep learning algorithms. In practice, many methods work best after the data has been normalized and whitened. However, the exact parameters for data preprocessing are usually not immediately apparent unless one has much experience working with the algorithms. In this page, we hope to demystify some of the preprocessing methods and also provide tips (and a "standard pipeline") for preprocessing data. == Feature Normalization == D == PCA/ZCA Whitening == How to choose epsilon? Do we need low-pass filtering? == Large Images == 1/f Whitening == Standard Pipeline == == Model Idiosyncrasies == === Sparse Autoencoder === ==== Sigmoid Decoders ==== ==== Linear Decoders ==== === Independent Component Analysis ===
