Simple Neural Network Transfer Function for 1 to -1 Output
I am new to Neural Networks and currently in need of guidance for a question I was presented with.
Question: Consider a single-input neuron with a bias. We would like the output to be -1 for inputs less than 3 and +1 for inputs greater than or equal…

A concern about the bias node in ann
OK so I get the idea of the bias node. It moves the transfer function curve horizontally to make it better fit the data. The problem I see is that the bias node weight value is computed just like any other weights. Is this right? Should the bias…

Interpreting neurons in the neural network
I have come up with a solution for a classification problem using neural networks. I have got the weight vectors for the same too. The data is 5 dimensional and there are 5 neurons in the hidden layer.
Suppose neuron 1 has input weights w11, w12,…

Simple neural network multiply training on untrained data gives big errors
i have made small multiplication neural network by using encog library with sigmoid activation function on the basic network.
My problem is i got big errors on untrained datas.
How can i enhance untrained data more good results.Less error…

Why do we have -1 and +1 as binary inputs instead of 0 and 1
I'm trying to get started with neural network and implement boolean functions like AND/OR.
Instead of using 0, and 1 as binary inputs, they use -1 and +1. Is there a reason why we cannot use (0, 1)?
As an example:…

Neural Network bias
I'm building a feed forward neural network, and I'm trying to decide how to implement the bias. I'm not sure about two things:
1) Is there any downside to implementing the bias as a trait of the node as opposed to a dummy input+weight?
2) If I…

Is the Bias unit in neural networks always one?
I have been studying Neural Networks for a couple of weeks and noticed that all guides and documentation either never mentioned the Bias unit and/or always assumed it to be 1.
Is there any reason or cases where we want a bias unit not to be 1?
Or…

Smartest neural network architecture
I am very new to neural networks and only a lowly programmer. I don't have a firm grasp of the different neural network architectures. My question is this: what is the smartest architecture? Which network is the fastest learning, can recognize the…
