Abstract

fetched live from OpenAlex

My research attempts to address on-line action selection in reinforcement learning from a Bayesian perspective. The idea is to develop more effective action selection techniques by exploiting information in a Bayesian pos-terior, while also selecting actions by growing an adap-tive, sparse lookahead tree. I further augment the ap-proach by considering a new value function approxima-tion strategy for the belief-state Markov decision pro-cesses induced by Bayesian learning. Bayesian Reinforcement Learning Imagine a mobile vendor robot (“vendorbot”) loaded with snacks and bustling around a building, learning where to visit to optimize its profit. The robot must choose wisely between selling snacks somewhere far away from its home

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
