PCA is a linear transformation with a well defined inverse transform and decoder output from autoencoder gives us the reconstructed input. We use 1 dimensional latent space for both PCA and autoencoders.
Nettet20. okt. 2015 · If you still want to try doing feature selection, I'd recommend χ 2 (chi-squared) feature selection. To do this, you rank your features with respect to the objective. χ 2 ( D, t, c) = ∑ e t ∈ 0, 1 ∑ e c ∈ 0, 1 ( N e t e c − E e t e c) 2 E e t e c, where N is the observed frequency of a term in D, E is its expected frequency, and t ... Nettet27. jul. 2015 · You can play around with a number of hidden units, though, but don't expect RBM being training at the same speed as SVM or logistic regression, for example. Note, that if your data has a notion of locality (e.g. nearby pixels on an image or words in a text), you can also try out convolutional networks which have much smaller weight …
