This document describes the formulation of an artificial neural network (ANN) model for a human-powered oil press. The researchers conducted experiments to collect data on the oil press's input and output parameters. They developed mathematical models to relate the parameters but also created an ANN model to better handle the complex, nonlinear relationships. The ANN was trained on the experimental data and can now predict the output values corresponding to given input values, providing a "best fit" model for the oil press system. The ANN model allows entrepreneurs to select optimal input combinations to maximize oil extraction and minimize torque/velocity, improving productivity.
