  • Developing and deploying machine learning applications to forecast meteorological time series. In this project, I built a Bayesian machine learning model based on the Gaussian Process Regression (GPR) methodology to forecast the meteorological parameters such as terrestrial evapotranspiration (ET) and rainfall. This model takes an auto-regressive approach where each value in the time series is predicted based on a few previous data points. Our model benefits from the Particle Swarm Optimization (PSO) technique to optimize the hyper-parameters of the adopted GPR kernel. Codes and more details are available here: https://github.com/ekourkchi/cropNet
