### How do you feed sets of connected data elements to an artificial neural network?

I'm currently working on a neural network to try to predict movements of electricity prices in a big city with multiple power companies to choose from. I know from a friend in the industry that power ...

### Neural networks: No solutions for test data possible?

So there are two ways of teaching a neural network as far as I am aware of. You supply the AI with test data and the correct solution to the problem. After some time the network will be able to get ...

### What are the practical uses of a neural network?

Even as an outsider to neural network development, they still seem to be a hot topic... I get lots of projects I see being starred on my GitHub homepage relating to neural networks. These projects ...

### Vector input for Artificial Neural Network?

My problem is fairly complex, so here is a similar, simplified example. Let's say you wanted to predict the Miles Per Gallon (fuel consumption) of a car, based on the following information: you have ...

### Is sparsity parameter really useful?

To make a sparse autoencoder,one way is add something to the function we want to minimize,which the further do average activity of hidden units to a sparsity parameter,the bigger your added thing will ...

### How can you write an activation function in a neural network to handle a layer architecture of arbitrary dimensions?

I am making a neural network in Clojure that can take an array of integers,and return a data structure representing the layers of a neural network: so (make-layers [1 4 5]) would evaluate to: [[0] ...

### To what values should you initialize the neurons and connection strengths in a neural network?

The values of all of the neurons in my neural network are initialized to 0 and the connection strengths between the neurons are set to randomly generated floats, between 0 and 1. I have seen other ...

### Can symbolic AI 'learn' a data model?

Perceptrons, a simple form of supervised machine learning, must be trained with a set of known good inputs before they can "learn" by adjusting internal weights assigned to inputs, based on the ...

### An Introductory Tutorial for Neural Net Backpropagation with Simplified Math

I built a neural net, and planned on optimizing the weights using a genetic algorithm. I was informed though, that this isn't a good idea, and to look into backpropagation. I searched around, and ...

### Is the output of a neural net supposed to have had the activation function applied to it?

TL; DR: Is the output from a feed-forward neural a direct result of the activation function? I.e: If the activation function is the sigmoid function, will the output always be between 0 and 1? I'm ...

### How to evaluate a recurrent connection in an artificial neural network?

I just can't understand how should I compute the output of a neural network, which contains a recurrent connection. So here is an example: (i_1,2 are the input values, w_1,2,3,r are the ...

### What parallelization methods can make neural nets train faster?

A fairly straightforward way (on a theoretical level, at least) of parallelizing artifical neural networks (ANNs) would be to divy up the batches of training examples during every epoch so that ...

### Neural network input preprocessing

It's clear that the effectiveness of a neural network depends strongly on the format you give it to work with. You want to pre-process it into the most convenient form you can algorithmically get to, ...
