Artificial neural networks are computational models inspired by biological nervous systems, capable of approximating functions that depend on a large number of inputs. Neural network vector representation - by encoding the neural network as a vector of weights, each representing the weight of a connection in the neural network, we can train neural networks using most meta-heuristic search algorithms. In the previous sections we've discussed the static parts of a Neural Networks: how we can set up the network connectivity, the data, and the loss function. Since neural networks are great for regression, the best input data are numbers (as opposed to discrete values, like colors or movie genres, whose data is better for statistical classification models).
