# Add Fading Table to all Discrete Nodes

Before performing adaptation on a network, one might consider adding fading tables to the nodes, since this allows “old” values to be faded out, so that the newest learned values carry a higher weight. The “Add Fading Table to all Discrete Nodes” function is a utility function, which add these to all relevant nodes. It can be accessed by selecting the “Add Fading Table to all Discrete Nodes” item from either the Network Menu, or from the popup menu (brought up by right-clicking on the network).
