The studies in a city have shown that water consumption is a function of three climatic variables, including precipitation, weather humidity, and average temperature. The monthly data of water consumption, monthly rainfall, monthly average humidity, and temperature of this city are given in Tables 9.2 –9.5. The studies have also demonstrated that the relation of water consumption with these parameters is complicated and cannot be formulated in regular form. Develop an MLP

model to simulate the monthly water consumption of this city as a function of monthly precipitation, humidity, and temperature.
