Abstract

fetched live from OpenAlex

Reinforcement learning (RL) has been successful in a variety of domains ranging from solving difficult games like Go [10] and drug discovery [4]. Most of these domains are characterized by high-dimensional states and continuous action spaces. However, sample inefficiency is a major challenge when applying these algorithms to real-world tasks such as robotics and healthcare care [6]. To address improved sample efficiency, rather than forcing agents to learn from scratch, domain knowledge from humans or existing agents can be leveraged in various ways [3].

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.

Full frame distilled prediction

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.
