| Summary: | Accurately forecasting the Remaining Useful Life (RUL) of lithium-ion batteries is essential for maintaining reliability and maximizing the performance of battery powered systems. Traditional Random Forest Regression (RFR) techniques have demonstrated strong accuracy but often face computational challenges as data dimensionality grows. Random Projection Forests (RPF) offer a promising solution by integrating random projections into the ensemble framework. They retain the predictive capabilities of RFR while significantly reducing computational overhead. This dissertation investigates the application of RPF and RFR algorithms to lithiumion battery RUL prediction, evaluating their accuracy, scalability, and adaptability to complex, high-dimensional data. The findings show that RPF achieves predictive performance comparable to RFR, yet with improved computational efficiency, thereby providing practical guidance for implementing more effective and resource-efficient battery management strategies. |
