• Developed a machine learning pipeline for predicting the QOS (quality of service) of a 5G mobile network using environmental variables (temperature, longitude, latitude) and RF measurements (RSRP, SNR, bandwidth). • Trained the pipeline on the Berlin V2X dataset achieving 7.97 mbit/s RMSE in predicting the QOS of the test split. • The pipeline used CatBoostRegressor . And incorporated feature engineering (one hot encoding, lag features) and hyperparameter tuning to improve performance.
