WebSep 11, 2024 · A Recursive Neural Network is a type of deep neural network. So, with this, you can expect & get a structured prediction by applying the same number of sets of weights on structured inputs. With this type of processing, you get a typical deep neural network known as a recursive neural network.These networks are non-linear in nature.
