Sustainable AI-Based Prediction of Air Pollution Levels in London
Bibliographic record
Abstract
Air pollution exposure not only leads to respiratory and cardiovascular diseases, but is also detrimental to cognitive abilities, mental health, and prenatal development. Thus, cities worldwide have invested in sophisticated air pollution monitoring systems to assess and reduce air pollution and its consequences. When excessive build-up of air contaminants occurs, emergency measures must be enacted to reduce human exposure and decrease pollution levels. Predicting such situations a few hours in advance is critical to prevent human health from being compromised. While usage of deep neural networks has become very popular, standard machine learning approaches remain very attractive: they deliver competitive performance, they do not rely on specialised equipment, and their energy consumption is sustainable. Experiments conducted on London air quality data demonstrate that Linear Regression achieves state-of-the-art performance, with 1-hour and 24-hour predictions displaying, respectively, 0.2 and 3.2 mean absolute errors. Moreover, its power usage is a fraction of what is required by its deep learning competitor for both training and predicting, i.e., 1/2840th and 1/126th, respectively. This is significant as they demonstrate air pollution prediction can be sustainable and accurate without prohibitive hardware investments.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
