Online Distributional Prediction via Latent Cluster Geometry Under Drift and Corruption
Researchers have developed a novel online learning method for predicting full data-generating distributions in non-stationary data streams, even when subjected to drift and adversarial corruption. The approach utilizes a latent cluster geometry to represent candidate probability laws, enabling online prediction through posterior averaging. This method avoids the need for parametric models of the data stream, drift, or corruption, offering theoretical guarantees for sublinear cumulative Wasserstein regret under specific conditions. AI
