Hello, I've decided to look into the subject of AI programming, and am having trouble with changing my weights with the delta rule. I'm trying to make a simple Boolean AND logic perceptron, which will learn to recognize whether both the inputs are the same.
Here's my code that I have so far:
There is no problem, except once I "train" the perceptron, and the feed it 2 inputs like 1 and 0, it would evaluate to true, but seeing both the inputs aren't true, it shouldn't.
// Include header files
using namespace std;
// Delcare vars
double threshold = 1.0;
double weight = -0.2;
int input1, input2;
// Keep looping
// Get the input vars
cout << "Please enter the first boolean input: ";
cin >> input1;
cout << "Please enter the second boolean input: ";
cin >> input2;
// Get the activation
activation = (input1 * weight) + (input2 * weight);
// If the activation is greater than the threshold, fire the perceptron
if (activation >= threshold)
cout << "Perceptron is firing" << endl;
output = true;
// If the activation is less than the threshold, don't fire
else if (activation < threshold)
output = false;
cout << "Perceptron isn't firing" << endl;
cout << "Changing Weights..." << endl;
cout << "Old Weight: " << weight << endl;
// Change the weights
weight += (input1 + input2) * (1 - output);
cout << "New Weight: " << weight << endl;
I don't know, but it may be the way I'm adjusting the weights, I'm using the delta rule off the cprogramming tutorials, and I may have interpreted it wrong.
I will admit right now that I'm just starting in this subject, so it's probably some simple mistake, or something that I've overlooked. If anyone has any suggestions, or a solution, it would be appreciated.
