Abstract
This paper addresses the problem of optimizing sensor deployment locations of a wireless sensor network to reconstruct and also predict a spatiotemporal signal. Traditional sensor deployment optimization approaches only selects deployment locations and provide the feature in the sampled area. Hence, if the sampling resources are limited, the deployed sensors may not be able to provide all features in the field of interest (input space). To solve this issue, a deep learning framework is developed to reconstruct and predict the entire spatiotemporal signal from a limited amount of observations. In the beginning, the proposed approach optimizes sampling locations to retrieve sufficient features for reconstruction and prediction from historical data. Then, a spatiotemporal autoencoder is used to capture the nonlinear mappings from the in-situ measurements to the entire spatiotemporal signal. A simulation is conducted using global climate datasets from the National Oceanic and Atmospheric Administration, to implement and validate the developed methodology. The results demonstrate a significant improvement made by the proposed algorithm. Specifically, compared to traditional approaches, the proposed method provides superior performance in terms of both reconstruction error and spatial prediction robustness.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
