In this study, neural networks are used to predict rainfall time-series. This rainfall is grows quickly because of complex geography of Japan. This means that it is more difficult to predict than other rainfall events. The former is a conventional one and the latter is added a context layer to the LN, but they only save the value of the hidden layer. Detail for ERNN is described in a later section.
Biological brain is interconnected by neuron mainly.
The memory is not stored in neuron itself, but stored by distributed thousands of interconnected neurons. Currently, most ANN program is running on the conventional computers. In these advanced system, real neuron behavior is only simulated by software program. But this kind of chip is not developed at this time. The fields of neural network approach are pattern recognition, system modeling and data compression.
