Question from the Machine learning - Fundamentals test

developers can modify the neural network structure and its learning parameters (number of hidden layers, error function, type of network…)

Developers can’t directly modify the model “internal” parameters (example: one can’t modify by hand a given input’s weight)

Developers can modify anything they want by hand (features you want to focus on, inputs’ weights, number of input layers…)

developers can’t modify the neural network learnings parameters : these are standard parameters
