    Does Research Exist on Biological Neural Network Chips?

    I have seen articles dealing with the growth of brain cells using stem cells. I have also seen, in the past, research attempting to mimic neural connections (using traditional silicon chips) for use in computing. I have searched for any mention of research into using actual living brain cells...

    Trouble with Neural Network coding

    I'm trying to make a neural network in python, but I'm having a lot of trouble. Specifically after I have the network set up, what weights to initially assign to each neuron's inputs, the threshold, and evolving the networks to do what you want. Here is my neuron class. class Neuron...

    Neuroscience Neural impulse, references and ideas

    Hello people, I would like some references, be it book or papers about the process of neural impulses at a single neuron level. My only reference so far is a book from 1974 (Stochastic models in biology) and so is probably outdated despite having around 30 pages on the subject. The more...

    Why Did My Neural Network Fail with Single Input Parameter?

    Hello, I'm interested in neural network programming but I am a beginner. Recently I wrote an example in C++ that I found in a book. It was a feedforward 3 layers network that learns the examples with the backpropagation algorithm. The aim of the network was to learn to "throw a stone": I taught...
