The proposed method introduces an optimal strategy for streaming contexts with limited labeled data. It presents an adaptive technique for unsupervised regression that leverages a sparse set of initial labels and incorporates an innovative drift detection mechanism to enable dynamic model adaptations in response to evolving patterns in the data.
The framework initially trains two regression models on independent datasets of different sizes. As new data flows into the streaming algorithm, it vigilantly monitors for drift using the ADWIN (ADaptive WINdowing) algorithm and error generalization based on Root Mean Square Error (RMSE). Upon detecting drift, the model is promptly retrained to align with the evolving data distribution, ensuring that it stays accurate and aligned with the changing reality of the data.
The authors evaluate the performance of their multivariate method across various public datasets, comparing it to non-adapting baselines. Through comprehensive assessments, they demonstrate the superior efficacy of their adaptive regression technique for tasks where obtaining labels in real-time is a significant challenge. The results underscore the method's capacity to outperform traditional approaches and highlight its potential in scenarios characterized by label scarcity and evolving data patterns.
