Truthful Online Preference Aggregation for LLM Fine-Tuning in Mobile Crowdsourcing

arXiv:2605.24052v1 Announce Type: new Abstract: To better serve users' demands in mobile applications (e.g., navigation), mobile crowdsourcing platforms can iteratively align large language model (LLM)-generated content (e.g., AI-generated traffic condition predictions) with human feedback collected from crowdsourcing workers (e.g., mobile users). However, workers may strategically misreport their online preference feedback to maximize their influence or payment. Existing pipelines in mobile crowdsourcing (e.g., EM-based weight estimation) fail to identify the most accurate worker in this onli

Why this matters
Why now

The proliferation of LLMs in mobile applications necessitates robust, truthful feedback mechanisms to ensure model alignment and performance, making this research timely.

Why it’s important

This research addresses a critical challenge in fine-tuning LLMs with human feedback in crowdsourcing, proposing methods to counter strategic misreporting and ensure data integrity.

What changes

The ability to more reliably aggregate human preferences for LLM fine-tuning in crowdsourced environments improves model accuracy and trustworthiness, enabling broader deployment.
