The Mechanical Neural Network(MNN) - XOR

The MNN adapted to the XOR logical operator.

The Mechanical Neural Network is a mechanical implementation of a Multilayer Perceptron with ReLU activation functions. Thus, it can model logical functions, including exclusive or but also real valued functions. It is build from wooden levers, which represent the neurons. This levers are linked by strings, corresponding to the connections between the neurons of a MLP. Adjusting the clamps, which connect the strings to the levers, by hand allows to adjust the weights of the network. Thus, the effect of adapting the weights can be intuitively observed.
