Feedforward neural networks are one of the simplest types ofneural networks, capable of learning nonlinear patterns and modeling complex relationships. In machine learning, an FNN is adeep learningmodel in the field ofAI. Unlike what happens in more complex neural networks, data in an FNN moves ...
Computing the gradient is slightly more complicated for a neural network than other traditional machine learning models, but can still be done efficiently and exactly by the back propagation (BP) algorithm, i.e. computing the chain rule ∂Tn∂T0=∑path∂Tn∂Tn−1∂Tn−1∂Tn−2...
