What is Feed-Forward & Feed-Back (Recurrent Connection)?

1. Feed-Forward Network Connection: This is the simplest neuron connection type in which data flow is in one direction only from Input Layer  -> Hidden Layer -> Output Layer.

 

 

 

 Re-current or Feedback Network Connection:  In this data flow is in back direction too, looping occurs, like Input Layer -> Hidden Layer -> Hidden Layer -> Hidden Layer  -> output Layer.
