PETSA: Parameter-Efficient Test-Time Adaptation for Time Series Forecasting
PETSA offers a parameter-efficient solution for Test-Time Adaptation (TTA) in time series forecasting, addressing the performance degradation caused by non-stationary data. It adapts pre-trained models during inference by updating small calibration modules, reducing memory and compute costs. This method, which includes low-rank adapters, dynamic gating, and a specialized loss, improves forecasting accuracy across diverse backbones and datasets.
Prometheus: The Monitoring System and Time Series Database
Prometheus is an open-source systems and service monitoring system, part of the Cloud Native Computing Foundation. It excels at collecting metrics as time series data, evaluating rule expressions, and triggering alerts. Its multi-dimensional data model and powerful PromQL query language make it a robust choice for modern observability needs.
