TopoBrick: Agentic Topology Sampling of Exogenous Variables for Zero-Shot Building IoT Forecasting
Researchers introduce TopoBrick, a training-free framework that uses agentic topology sampling to improve zero-shot forecasting for building IoT sensors by leveraging building knowledge graphs.
- TopoBrick is a training-free framework for zero-shot building IoT forecasting, eliminating the need for labeled training data.
- It uses building knowledge graphs to create a structural skeleton and agentic topology sampling to select relevant exogenous variables.
- The method organizes variables by deployment-time availability, separating past-known states from future-known covariates.
- This approach addresses the limitations of traditional methods that treat sensors as isolated time series.
A new research paper presents TopoBrick, a training-free framework designed to address the limitations of traditional building IoT forecasting methods. Most existing approaches treat building sensors as isolated time series or rely on fixed sets of covariates, ignoring the physical topology, spatial hierarchy, and operational context of the sensors. TopoBrick introduces a novel approach by constructing a compact structural skeleton using building knowledge graphs and employing an agentic topology sampler to dynamically select target-specific exogenous variables.
The framework organizes selected variables based on their deployment-time availability, distinguishing between past-known sensor states and future-known covariates. This method enables zero-shot forecasting, meaning it can make accurate predictions without requiring prior training on specific datasets. The approach is particularly relevant for large-scale building management systems where sensor data is abundant but labeled training data is scarce.
The research highlights the potential of agentic systems in improving the accuracy and adaptability of IoT forecasting models, especially in complex environments like smart buildings.
