QueryMarket: Cost-Aware Online Active Learning in Data Markets

arXiv:2606.17805v1 Announce Type: new Abstract: Data acquisition is a major bottleneck for learning in real-time streams: analysts must decide on the fly which labels to purchase while respecting a rolling budget. However, existing online active learning rarely unifies pricing, information gain, and rolling budget constraints under concept drift. We introduce QueryMarket, a market-inspired framework that queries each incoming data point based on its estimated utility to the model and its price. Within this framework, we propose OVBAL (online variance-based active learning), which integrates da

Why this matters
Why now

The increasing scale and cost of data for AI models, especially in real-time or dynamic environments, necessitates more efficient data acquisition strategies.

Why it’s important

Efficient and cost-aware data acquisition in online learning directly impacts the development and deployment of more agile and cost-effective AI systems, crucial for competitive advantage.

What changes

Data market participants will have a framework to optimize data purchasing under budget constraints, integrating pricing and information gain, which will influence how AI models are trained and updated.

Winners
