The recent developments in the research area of machine learning applications, particularly in energy forecasting and customer churn prediction, have shown a strong emphasis on enhancing model explainability and real-time decision-making capabilities. In energy forecasting, there is a notable shift towards more granular, household-level predictions, addressing the need for both accuracy and interpretability. This trend is complemented by advancements in real-time model selection using e-values, which provide probabilistic guarantees for dynamic environments, enhancing the reliability of forecasts in the energy sector. On the other hand, in customer churn prediction, the integration of fuzzy-set theory with machine learning models has led to innovative methods that improve the explainability of churn patterns, offering valuable insights for businesses. These developments collectively push the boundaries of current methodologies, making them more adaptable and insightful for practical applications.

Noteworthy papers include one that introduces a custom decision tree for household energy forecasting, balancing accuracy with explainability, and another that employs e-values for real-time model selection in energy demand forecasting, significantly improving the reliability of predictions in dynamic settings.
