Bugs: Incoherent bias neuron behavior #24

Closed ydawei closed 7 years ago

ydawei commented 7 years ago

I manually specified DontUseBiasNeuron=True in the parameter, but in Genome::Mate(...) it still adds a bias neuron.

Also, the NeuralNetwork::Input(..) function ignores bias neuron and views the bias neuron as an input neuron.

Thanks, I'll take a look.

The problem in Genome::Mate() was fixed recently. NeuralNetwork::Input() is supposed to ignore the bias. At the point of activating the NN all inputs are treated equal. The bias isn't given a value of 1.0 automatically, the user has to supply it.
