Abstract

fetched live from OpenAlex

The proliferation of wireless sensors in everyday consumer products presents new opportunities to monitor the environment at unprecedented space and time scales. This study explores the utility of pervasive sensors for improving the resolution of areal precipitation estimates through fusion with weather radar observations. While these sensors are not specifically designed to measure rainfall intensities, the data they collect can be repurposed to provide quantitative measurements of environmental variables at the location of the sensor. Due to different measurement accuracies (which may be time dependent), types of spatial and/or temporal measurement support, and measurement frequencies of the component sensors, it is unclear how best to combine measurements from pervasive sensors with those from traditional sensors. The method developed in this study employs Markov random field models to compute the likelihood of rainfall at sub-grid pixels. These likelihoods are used to "unmix" the block-averaged rainfall rate measured by the radar. The statistical nature of the model permits the data evidence to drive the fusion of the sensors' measurements. The performance of these methods will be illustrated using case studies exploring synthetic and real-world data.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
