Templated or fully synthetic? Prompt construction as a confound in measuring LLM political stance beyond writing assistance
Ilias Chalkidis
Political stance detection in LLMs has long been dominated by closed-ended, multiple-choice political survey questions---originally designed for humans, and thus lacks the realism…
Convergence Analysis of Two Alternating Iterative Schemes for Tucker Decomposition
Ren-Cang Li, Li Wang, Mei Yang
The higher-order orthogonal iteration (HOOI) and the alternating subspace iteration (ASI) are two popular numerical methods for computing the Tucker decomposition of a multiple-mod…
An NPDo Approach for Tensor Block-Diagonalization
Ren-Cang Li, Li Wang, Mei Yang
This paper is concerned with Partial Tensor Block-Diagonalization of a multiway tensor by orthonormal matrices so that the extracted block-diagonal part optimally represents the te…
An NPDo Approach for Principal Joint SVD-type Block Diagonalization
Ren-Cang Li, Li Wang, Mei Yang
This paper is concerned with partial Joint SVD-type Block Diagonalization of several matrices so that the extracted diagonal parts collectively optimally assume part of the total m…
