Estimating Large Language Model Capabilities without Labeled Test Data

1 code implementation24 May 2023 Harvey Yiyun Fu, Qinyuan Ye, Albert Xu, Xiang Ren, Robin Jia

In this paper, we propose the task of ICL accuracy estimation, in which we predict the accuracy of an LLM when doing in-context learning on a new task given only unlabeled test data for that task.

Mathematical Justification of Hard Negative Mining via Isometric Approximation Theorem

no code implementations20 Oct 2022 Albert Xu, Jhih-Yi Hsieh, Bhaskar Vundurthy, Eliana Cohen, Howie Choset, Lu Li

In this paper, we utilize the mathematical theory of isometric approximation to show an equivalence between the Triplet Loss sampled by hard negative mining and an optimization problem that minimizes a Hausdorff-like distance between the neural network and its ideal counterpart function.
