Abstract
Aim: We seek to assess the performance of time delay neural networks (TDNN), one of the topologies designed for time series prediction, to characterize spectrum occupancy in multiple time horizons in Land Mobile Radio bands. This could lead to dynamic spectrum allocation methods to address potential spectrum shortages facing Internet of Things (IoT) deployments. Background: ANNs are a popular choice for spectrum prediction. Traditionally, ARIMA models have been at the forefront of forecasting and prediction but ANNs that learn from time series have demonstrated good performance using both simulated datasets and real-life data collected in the cellular bands. Methodology: We use three prediction models, a baseline which simply delays the time series, a seasonal ARIMA model and a TDNN. We test their performance on an hourly dataset in LMR bands collected in Ottawa, Canada between the dates of October 2016 and April 2017. Results: We demonstrate that TDNN yields improvements over seasonal ARIMA models in predicting short time horizons. Conclusions: The TDNN based prediction models that are designed to work with time series data provide a better alternative for accurately predicting spectrum occupancy in bands that exhibit similar characteristics to LMR channels, especially as the forecast horizon gets longer.

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
