	# Neural PCA/Compression in R

	In this document I will show a small experiment that shows how a neural network can be used as a pca-algorithm. It should also help explain how neural networks work and why neural networks can be such a powerful machine learning algorithm.

	### Packages Used

	```{r packages}
	library(RSNNS)
