Genetic Machine Learning Framework

Autonomous evolution: From simplest to complex

This is an evolutionary genetic AI framework that designs itself (AutoML). I believe the most powerful AI is the one which creates itself. A complex structure that human cannot understand, like our brains.

Solve XOR example:

php xor.php

Main Parts

World, Agent, Neuron, GeneEncoders, Activation functions, Reproduction

Layering

These 2 neural networks are identical. All hidden layers can be combined into a single layer with intra-connections.

This way we eliminate the need for manual configuration of neuron and layer counts. This single hidden-layer gets very complex and not understandable for humans after several generations of evolution by genetic algorithm. This is not important for us because we don't want to analyze them. We just want to make the network powerful, and indeed it will be very powerful.

Example:

$data = [
    [[0, 0, 0], [1]],
    [[0, 0, 1], [0]],
    [[0, 1, 0], [0]],
    [[0, 1, 1], [1]],
    [[1, 0, 0], [1]],
    [[1, 0, 1], [0]],
    [[1, 1, 0], [0]],
    [[1, 1, 1], [1]],
];
