Abstract

fetched live from OpenAlex

Diversity is a key element in the success of classifier ensembles, and has attracted much recent attention. It is typically measured by directly computing the amount of disagreement between ensemble classifiers at the decision level. This costly process usually involves evaluating output predictions of each classifier over some validation data set. Since most statistical and neural network classifiers can adjust internal learning dynamics by varying their hyperparameter values (corresponding to genotype values), this information can also provide an estimate of diversity. This paper measures the correlation between genotype and classifier diversity among an ensemble of fuzzy ARTMAP neural network classifiers applied to video face recognition. It is empirically shown that as genotype diversity increases within an ensemble, classifier diversity also significantly increases. This correlation can then be exploited to measure the diversity among base classifiers during ensemble design with a significantly lower computational cost.

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.

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.
