Distribution shift analysis
Model performance is compared between training data and deployment data to detect shifts in inputs or labels that reduce accuracy, with monitoring set up to catch drift.

Artificial intelligence and machine learning is the technology this platform stewards for the network. Here it is studied as a technology whose behaviour must be understood: how models learn from data, generalise, fail outside their training distribution and are adapted to specific uses.
Artificial intelligence and machine learning develop algorithms that learn patterns from data to classify, predict or generate outputs. They are increasingly used for hazard detection, forecasting and decision support, and are themselves a source of risk. In artificial intelligence and data and compute, machine learning can scale detection and forecasting across interconnected pergalan. Its own failure modes must be weighed when automated outputs inform consequential decisions. The canonical description is on STEM Commons.
Model performance is compared between training data and deployment data to detect shifts in inputs or labels that reduce accuracy, with monitoring set up to catch drift.
General models are adapted to a narrow task with curated data, and the adapted model is evaluated for both task performance and retained safety behaviour.
Feature attribution and probing methods are used to examine which inputs drive a model’s outputs, with their limits as explanations stated.
Her ajan dema ku têra têkiliyên wê kiriye tevdigere; guherînên piçûk di sînora navîn an di yên pêşîn de diyar dikin ka tevger herêmî dimîne an di nav nifûsê de kaskade dibe. Modela hînkirinê bi nirxên ronîker ên diyarkirî, ne pêşbînî.

Models are evaluated on held-out data that respects spatial, temporal and group structure. Robustness, calibration and fairness are tested alongside accuracy.
| Kontrol bikin | How it is done |
|---|---|
| Held-out evaluation | Models are evaluated on data not used for training or tuning |
| Dataset documentation | Training data carry datasheets on origin, consent and limits |
| Drift monitoring | Deployed models are monitored for input and performance drift |
Performance degrades when deployment conditions differ from training data. Models can encode biases and fail without clear warning on rare events.
