smarty-bird

This is a reproduction of the game “Flappy Bird” with a genetic deep neural network AI, made by Luxedo and Faifos. The game is made using p5.js and nothing more.

Besides playing the regular game, you can train a neural network that has 4 inputs and a bias term. The deep layer has 3 neurons and another bias. The output is a single neuron. All of the neurons uses tanh as the activation function. The bird flaps its wings if the output neuron is activated (if it has a positive value).

The network is trained with a genetic algorithm. The best bird is allowed to breed and fill 50% of the population. Variance is introduced by altering the neurons randomly with a 50% chance.

Let the birds train for a while and after some generations they will be better than you.
