# Can somebody help me explain multilayer neural networks?

I programming a neural network with 1 hiddel layer, but when I need more hidden layer, my program is not be able to use it. I read some paper about multi hidden layer, and these training methods(example backpropagation), but I dont understand a few thing, I really want to understand, or someone show me an understable code. When I try to programming multilayer training, and prediction, something not working, so I would be grateful if someone link here a code example for multi hidden layer neural network (I written with java)

That's fine. It's for the sake of easy understanding to break stuff into modules.

Did you model classes properly ? We have a Simple Cell class, with Input, Output class, Layer class - map / array of Simple Cells, Network class - List of Layer objects.

This is more of an LLD problem than of machine learning.

Google my man, just google - neural network implementation from scratch in java.

Use multiple threads to run different nodes on different cores. Nvidia does it very nice on GPUs.

I learnt in university and I did Andrew Ng free course around 3 years ago.

there is website called machinelearning.com i guess

Cool, have fun.

Did you learn about integration & differentiation in math ? Think of hidden layer's input as new neural network and try to recursively build logic.

I am not working multiple classes, I have 1 class, and the layers weights I store in matrices

Can you souggest me, sites, or app where I can see multiple layer's property, and arhitecture?

Thanks, and what can I do for optimalize a big neural network example with 10000 hidden nodes?

Thanks, the tips, where are you learn about neural networks?

Thanks the helpingðŸ˜Š

I'd like to find a site, or any helping paper, about the backpropagation algorithm, because I think, I don't understand few thing in the method In single hidden layer network I understand then traiming, and the error calculation, but more complicatin in multilayer network

I did not learn about integration, and....., but I know about these math things(so I cant application these math things for a problem), do you suggest me, to learn more math?

yes, just the basics are enough
