Feedforward neural networks and recurrent neural networks are two different types of artificial neural networks.
A feedforward neural network is the most common type of neural network, where information flows only from the input layer to the output layer, without any feedback loops. This means that each node in a feedforward neural network is unidirectional, and information can only be transmitted in one direction. Feedforward neural networks are typically used for tasks such as classification, regression, and clustering.
On the other hand, recurrent neural networks have feedback loops, which allow information to be fed back from the output layer to the input layer or hidden layers. This enables recurrent neural networks to handle sequential data, such as time series, speech recognition, and natural language processing tasks. Nodes in recurrent neural networks can receive information from previous time steps and pass it on to the next time step, allowing them to capture temporal dependencies in sequential data.
Therefore, the main difference between feedforward neural networks and recurrent neural networks lies in their information flow and feedback mechanisms.
