Symmetrical ‘Super Learning’: Enhancing learning using a bidirectional probabilistic outcome
Bibliographic record
Abstract
In a learning scenario, with multiple positive or negative (excitatory or inhibitory) predictive cues of a single outcome, cues interfere with or enhance each other during the acquisition process (e.g., Baker et al., 1993). Previous experiments have primarily focussed on cues that signal the presence or absence of binary outcomes. This introduces a motivational and saliency asymmetry between excitatory and inhibitory learning. Here we asked whether learning about both generative (incremental positive outcome) and preventative (incremental negative outcome) causal cues show similar enhancement effects. In three experiments with humans using predictive learning tasks, participants (N = 133) were exposed probabilistic predictive cues for two opposite polarity events. Generative cues caused an increased outcome, while preventative cues decreased the outcome. Learning was assessed via explicit judgments of the relation between the cue and the outcome. We report evidence for symmetrical learning and enhanced learning for both generative and preventative cues. The results are discussed in relation to super learning, an effect derived from theories of competitive learning based on error correction, and from theories of contrasting probability estimates.

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.
