title: In neural networks, do bias terms have a weight?
body: <p>I am trying to code my own neural networks, but there is something I don't understand about bias terms. I know each link of a neuron to another neuron has a weight, but does a link between a bias and the neuron its connected to also have a weight? Or can I think of the weight always 1 and never gets changed?</p>
  
  <p>Thanks</p>
