AML4S: An AutoML Pipeline for Data Streams
Paper Category: Data Streams & Drift Detection
Traditional online machine learning (ML) and AutoML solutions for data streams struggle with diverse drift types, manual tuning, and limited model selection. We introduce AML4S, an end-to-end AutoML pipeline designed to automatically adapt to both concept drifts (changes in P(y|X)) and data drifts (changes in P(X)) in continuous data streams. By integrating a comprehensive search space for preprocessing, feature selection, and classification models with an ADWIN-based drift detection mechanism, AML4S ensures robust and continuous adaptation. Our methodology, implemented using the River framework, leverages a memory window for efficient retraining upon drift detection, making it suitable for real-time applications.
Quantifiable Enterprise Impact
AML4S significantly enhances the reliability and efficiency of machine learning in dynamic, streaming environments. By automating pipeline selection and hyperparameter tuning, it reduces operational overhead and the need for specialized ML expertise. Our evaluation demonstrates that AML4S consistently outperforms state-of-the-art online ML and AutoML methods, achieving up to 9% higher accuracy on synthetic datasets with complex drift patterns and maintaining superior performance on real-world streams like Covtype and Rialto. Furthermore, its rapid retraining capabilities (averaging ~15-25 seconds for most scenarios) ensure minimal downtime and continuous model relevance in fast-evolving data landscapes, translating to improved decision-making and operational agility for enterprises.
