During simulation, I encountered difficulties with the MATLAB :
1) Long-time execution: when executing to train the network, as the number of hidden units increase, the more time is needed to execute. But in order to obtain an accurate result, the units must be very large number.
2) Maximum memory: as the size of the network increases by increasing the units and layers, the computer is not able to execute the program because it takes up a lot of memory. This is also another cause of inaccurate results in simulations.
