Abstract

fetched live from OpenAlex

In large electronic marketplaces populated by buying and selling agents, repeated transactions between traders may be rare. This makes it difficult for buying agents to judge the reliability of selling agents, discouraging participation in the market. A variety of systems have been proposed to help traders to find trustworthy partners; however, most proposed systems suffer from multiple vulnerabilities that might be exploited by unscrupulous parties. In this paper, we propose a new model, wherein abstract units are used to represent trust in much the same way that units of money represent value. In a manner similar to money, 'trunits' flow during transactions. A trader's trunit balance determines if they are trustworthy for a given transaction. Faithful execution of a transaction results in a larger trunit balance, permitting the trader to engage in more transactions in the future---a built-in economic incentive for honesty. We demonstrate that for a wide range of realistic market parameters, the Trunits mechanism ensures that honest sellers profit more than dishonest sellers. We also discuss how intrinsic properties of our model make it secure from many of the attacks to which other systems are vulnerable. In summary, we present our Trunits model as the basis for modeling trust in electronic marketplaces, useful as buying agents develop algorithms to intelligently choose trustworthy sellers for their business partners.

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.
