Abstract
Data-driven applications often change over time by considering new features to improve predictive accuracy. Re-training a model from scratch for every change loses the learned knowledge and is very time-consuming. To fill the big literature gap, we devise an incremental feature learning algorithm using constructive neural networks to include new groups of features gradually and without re-learning from scratch. The algorithm dynamically constructs the final model by determining the optimal network topology leading to the best performance. We demonstrate our algorithm’s efficacy through a regression problem by evaluating the sequential models obtained after extending the feature space incrementally, using different feature rankings. We also assess our algorithm without feature grouping and with the non-incremental learning version.

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 it
