App developed with the idea of demonstrating the functioning of a neural network, with only three neurons, you can test using data like AND, OR and XOR, in your tests you will see that increasing interactions, adjusting the learning rate, will have a great effect on network performance, data is trained in order from top to bottom, so how you distribute your training data will affect the network. You will also see that often just three neurons will not be enough to achieve great results. I hope this simple app can help you in your studies.
