Context-Sensitive MTL Networks for Machine Lifelong Learning.
Bibliographic record
Abstract
Context-sensitive Multiple Task Learning, or csMTL, is presented as a method of inductive transfer that uses a single output neural network and additional contextual inputs for learning multiple tasks. The csMTL method is tested on three task domains and shown to produce hypotheses for a primary task that are significantly bet-ter than standard MTL hypotheses when learning in the presence of related and unrelated tasks. A new measure of task relatedness, based on the context input weights, is shown to have promise. The paper also outlines a ma-chine lifelong learning system that uses csMTL for se-quentially learning multiple tasks. The approach satis-fies a number of important requirements for knowledge retention and inductive transfer including the elimina-tion of redundant outputs, representational transfer for rapid but effective short-term learning and functional transfer via task rehearsal for long-term consolidation.

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.
