Variational Beam Search for Online Learning with Distribution Shifts.

TL;DR: A new Bayesian meta-algorithm is proposed that can both make inferences about subtle distribution shifts based on minimal sequential observations and accordingly adapt a model in an online fashion and yields significant improvements over state-of-the-art Bayesian online learning approaches.

Zero-Shot Batch-Level Anomaly Detection

TL;DR: Adaptive Centered Representation (ACR) as mentioned in this paper is a simple yet effective method for zero-shot batch-level anomaly detection, which trains off-the-shelf deep anomaly detectors to adapt to a set of inter-related training data distributions in combination with batch normalization.

Feature Model for Longitudinal Social Networks

TL;DR: It is shown how the number of features and their trajectories for each actor can be inferred simultaneously and the utility of this model on prediction tasks using synthetic and real-world data is demonstrated.

Climate-driven changes in the predictability of seasonal precipitation

TL;DR: In this article , on the basis of CMIP6 models that capture the present-day teleconnections between seasonal precipitation and previous-season sea surface temperature (SST), the authors show that climate change is expected to alter the SST-precipitation relationships and thus their ability to predict seasonal precipitation by 2100.

Bayesian Predictive Profiles With Applications to Retail Transaction Data

TL;DR: A generative mixture model for count data is described and an an approximate Bayesian estimation framework that effectively combines an individual's specific history with more general population patterns is used.
