Incorporation of State-Level Variable Stime-Varying Property into the HMM
Bibliographic record
Abstract
In HMM-based pattern recognition, the structure of the HMM is often predetermined according to some prior knowledge. In the recognition process, we usually make our judgment based on the maximum likelihood of the HMM, without considering the time-varying property of state-level variables, which unfortunately may lead to incorrect results. In this paper, we analyze the property of state-level variables in the HMM and show it is possible to significantly enhance the performance of speech recognition systems when using the state-level variable time-varying property. We propose to make use of the distribution of the number of intersecting points (NIPs) of state-level variable trajectories in the recognition process, which achieve 2.7 percent correct improvement to a phoneme classification task on TIMIT speech corpus. We also compare the proposed method and state duration model and draw some empirical conclusions

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
