From Retrieval to Customer Context: Evaluating Frontier-Model Systems for Voice-of-Customer Analysis
Raviraja G, Viraj Bagal, Prabhath Chellingi
Organizations increasingly use frontier language models to analyze customer feedback, but answer quality also depends on how that feedback is organized and made available. We defin…

New non-quadratic Euclidean complete affine maximal type hypersurfaces via Calabi affine geometry
Yalin Sun, Cheng Xing, Ruiwei Xu
The Bernstein problem for the affine maximal type equation \[ \sum_{i,j=1}^n f^{ij} w_{ij}=0,\qquad w\equiv \left[\det\left(\frac{\partial^2 f}{\partial x_i\partial x_j}\right)\rig…

Calabi affine maximal surfaces and centroaffine Bernstein problems
Yalin Sun, Cheng Xing, Ruiwei Xu
Motivated by Calabi's calculation of the second variation sign for locally strongly convex affine maximal surfaces in equiaffine geometry, we first prove that every Calabi extremal…
