Abstract

fetched live from OpenAlex

We propose to demonstrate the open source implementation of nfer (http://nfer.io), a language and system for abstracting event streams. The tool is applicable to a wide variety of cyber-physical systems, and supports both manual and mined specifications. In addition to basic operation, we will demonstrate standalone monitor generation and integration with the popular R and Python languages. The demonstration will use real-world data captured from applications such as an autonomous vehicle and a hexacopter.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
