Multi$-$Layer Feedforward Networks$)$ One method for dealing with local minima is to use a committee of networks. What does this mean?

A large number of different networks are trained and tested. The network with the lowest sum

X

squared error on a separate validation set is chosen as the best network.

A large number of different networks are trained and tested. All of the networks are used to solve the real$-$world problem by taking the average output of all the networks.

A large number of different networks are trained and tested. The networks are then combined
