2 layer newral network is added to n42
This network is simple newral network which can trained throught gradient descent optimization calculation.
It is the same algorithm to the one of denoised autoencoder used by n42. So implementation itself was not diffucult.
The code is showed below.

n42 has restricted boltzmann machine. Restricted boltzmann machine is a kind of
autoencoder in order to extract charasteristics. In this article, I would leave out
the detail of restricted boltzmann machine. I want to introduce how the RBM is written
in node.

I developed deep leanring module which enables you to use stacked denoised autoencoder in nodejs.
This is called n42. You can train with deep learning algorithm very easily.

Auto encoder is used for deep learning. Auto encoder extract characteristics of data through unsupervised learning. This is a kind of newral network. By using an auto encoder, you don’t have to be in trouble with choicing extracting algorithm, or doing yourself. Therefore, in deepleanring field, this algorithm is used...
