A Feedforward Neural Network (FFNN) is the simplest type of neural network. In this model, information moves only in one direction — from the input layer, through one or more hidden layers, to the output layer. There are no backward or side connections between neurons, and neurons within the same layer don’t interact with each other. Usually, every neuron in one layer is connected to every neuron in the next layer, which is called a “fully connected” structure.
