Abstract

fetched live from OpenAlex

A joint US-Canada task force has begun examining the blackout that affected large areas of the northeastern USA and Ontario, Canada. In September the North American Electric Reliability Council (NERC) released an outline of events before and during the cascade. The outline focuses chiefly on events that occurred on major transmission facilities and at large power plants. NERC says the outline "does not attempt to present or explain the linkages between the sequences of events that are described. Determining those linkages will require additional intensive analysis over the weeks to come." Investigators will first check that the timeline is correct The times derive from the `time stamp' in the data record. However, the investigators discovered that some time stamps were not accurate because the computers that recorded the information became backlogged, or the clocks from which the time stamps were derived had not been calibrated to the national time standard. Investigators must determine which events are accurately time-stamped, and build from those events to cross-check other system events from multiple sources to verify the precise time for each event. Some of these events are still not known to the exact second. This paper gives the time-line from the onset of the problem, 12:05:44 p.m., to the total blackout time of 4:13 p.m.

Full frame distilled prediction

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.
