arXiv:2501.06708v5 Announce Type: replace Abstract: Large-scale web-crawled datasets contain noise, bias, and irrelevant information, necessitating data selection techniques. Existing methods depend on hand-crafted heuristics, downstream datasets, or require expensive influence-based computations -- all of which limit scalability and introduce unwanted data dependencies. To address this, we introduce the Mimic Score, a simple and geometry-based data-quality metric that evaluates utility by measuring alignment between a sample's gradients and a target direction induced by a pre-trained referenc
The proliferation of very large AI models trained on vast, often noisy datasets makes efficient and scalable data selection techniques critical right now.
This research introduces a novel, geometry-based method for data quality evaluation that could significantly improve the efficiency and reliability of AI model training, reducing dependencies on costly and imperfect manual processes.
AI development could shift towards more efficient and less resource-intensive data curation, enabling broader participation and potentially reducing the computational barriers to entry.

More robust and less biased AI models can be trained with fewer computational resources.
The reduced cost of data curation could democratize access to advanced AI development, fostering innovation beyond well-funded tech giants.
This could accelerate the development of specialized AI agents or models tailored for specific, high-quality data scenarios, leading to more practical applications.
