Performance Evaluation of Tree-based Models for Big Data Load Forecasting using Randomized Hyperparameter Tuning

In this paper machine learning (ML) models have been developed for the application of big data load forecasting using parallel computation. The load forecasting models' performance is directly linked to system execution capacity, memory, thread count, balancing the load, and available resources. This paper is focused on two main challenges. The first challenge is to reduce the execution time of the ML models and the second one is to choose the suitable tree-based model for effective load forecasting. The paper conducts a comprehensive evaluation of the load forecasting using real-world data on energy consumption. Comprehensive results are obtained to show that the performance of random search to tune the ML models exhibits competitive performances whilst not losing the accuracy of the models and gaining a competitive advantage on the run time.
