Abstract

fetched live from OpenAlex

Observing and analyzing the changing polar ice patterns is crucial for understanding the climate crisis. Research works across the Circumpolar North use machine learning models to study and predict changes in sea ice. In this paper, we propose a deep learning model using satellite images of the Arctic, captured daily and monthly over a half-century period and curated at the National Snow and Ice Data Center (NSIDC), to forecast future ice extent. We perform a time-series analysis using a multimodal approach, combining a gated recurrent unit (GRU) with a transformer-based model to predict changes in Arctic ice. Our model explains approximately 92.02% of the variance in the true ice extent time series. The error metrics were low: We observed the Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) to be, respectively, 0.1362 and 0.1637. Preliminary assessments of our prototype show promising results in understanding past trends and making predictions.

Teacher imitation

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.
