This document describes research on developing models to predict Indian summer monsoon rainfall (ISMR). It presents an adaptive neuro fuzzy inference system (ANFIS) model, linear regression model, and nonlinear regression models including a sigmoid neural network model and wavelet network model. 142 years of historical rainfall data from India were used to develop and evaluate the models. The goal was to extract spatial and temporal rainfall patterns from past data to predict future rainfall, which is challenging due to the complex and variable nature of rainfall.
