What is Your Data Worth to GPT? LLM-Scale Data Valuation with Influence Functions

NeurIPS 2025poster

Large language models (LLMs) are trained on a vast amount of human-written data, but data providers often remain uncredited. In response to this issue, data valuation (or data attribution), which quantifies the contribution or value of each data to the model output, has been discussed as a potential…

Making Scalable Meta Learning Practical

NeurIPS 2023poster

Despite its flexibility to learn diverse inductive biases in machine learning programs, meta learning (i.e.,\ learning to learn) has long been recognized to suffer from poor scalability due to its tremendous compute/memory costs, training instability, and a lack of efficient distributed training sup…

On the Effect of Pretraining Corpora on In-context Learning by a Large-scale Language Model

NAACL 2022long

Many recent studies on large-scale language models have reported successful in-context zero- and few-shot learning ability. However, the in-depth analysis of when in-context learning occurs is still lacking. For example, it is unknown how in-context learning performance changes as the training corpu…
