Anticipation of summer monsoon rainfall over India by Artificial Neural Network with Conjugate Gradient Descent Learning

Abstract

Present study aims to develop a predictive model for the average summer monsoon rainfall amount over India. The dataset made available by the Indian Institute of Tropical Meteorology, Pune, has been explored. To develop the predictive model, Backpropagation method with Conjugate Gradient Descent algorithm has been implemented. The Neural Net model with the said algorithm has been learned thrice to reach a good result. After three runs of the model, it is found that a high prediction yield is available. Ultimately, Artificial Neural Network with Conjugate Gradient Descent based Backpropagation algorithm is found to be skillful in predicting average summer monsoon rainfall amount over India.
