Abstract

fetched live from OpenAlex

In this letter, we propose a novel approach of simultaneous feature and model selection for continuous hidden Markov model (CHMM). In our method, a set of real valued quantities, defined as feature saliencies, are proposed for feature selection. A variational Bayesian (VB) framework is applied to infer the feature saliencies, the number of hidden states, and the parameters of the CHMM simultaneously. Experiments based on synthetic and real data demonstrate the effectiveness of the proposed method.

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.
