There is a study on learning from examples in a two-layered committee neural network by using replica theory. The number of hidden units of the student network is assumed larger than the number of hidden units in the target (teacher) network. Both networks have same number of input and output units. One introduces first some basics in statistical mechanics and infinite degeneracy's. Discussed are the permutation-symmetric state and permutation symmetry breaking phase. Monte Carlo simulation results are shown to be in agreement with the theoretical experiments.
