Abstract

fetched live from OpenAlex

This paper introduces a computational intelligence approach to the problem of detecting internal changes within dynamic processes described by heterogeneous, multivariate time series with imprecise data and missing values. A data mining process oriented to model discovery using a combination of neuro-fuzzy neural networks and genetic algorithms, is combined with the estimation of probability distributions and error functions associated with the set of best discovered models. The analysis of this information allows the identification of changes in the internal structure of the process, associated with the alternation of steady and transient states - zones with abnormal behaviour - instability and other situations. This approach is rather general, and its potential is revealed by experiments with simulated and real world data.

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.
