Abstract: Concept Drift (CD) is a significant challenge in real-world data stream applications, as its presence requires predictive models to adapt to data-distribution changes over time. Our paper introduces a new algorithm, Probabilistic Real-Drift Detection (PRDD), designed to track and respond to CD based on its probabilistic definitions. PRDD utilizes the classifier’s prediction errors and confidence levels to detect specifically the Real CD. In an exhaustive empirical study involving 16 synthetic datasets with Abrupt and Gradual drifts, PRDD is compared to well-known CD detection methods. PRDD is highly performing and shows a time complexity of O(1) per datapoint, ensuring its computational efficiency in high-velocity environments.
