title: Global Weight Decay in Keras
body: <p>Is there a way to set a global weight decay in Keras?</p>
  
  <p>I know about the layer wise one using regularizers(<a href="https://keras.io/regularizers/" rel="noreferrer">https://keras.io/regularizers/</a>), but I could not find any information about a way to set a global weight decay.</p>
