TuneAhead: Predicting Fine-tuning Performance Before Training Begins

ICML 2026poster

Fine-tuning large language models (LLMs) is compute-intensive and error-prone: model performance depends sensitively on data quality and hyperparameter choices, and naïve runs can even degrade model performance. This raises a fundamental question: Can we predict fine-tuning performance before traini…

Structural-Entropy-Based Sample Selection for Efficient and Effective Learning

ICLR 2025poster

Sample selection improves the efficiency and effectiveness of machine learning models by providing informative and representative samples. Typically, samples can be modeled as a sample graph, where nodes are samples and edges represent their similarities. Most existing methods are based on local inf…
