Concept Heterogeneity-aware Representation Steering

Researchers introduce CHaRS (Concept Heterogeneity-aware Representation Steering), a new method for controlling large language model behavior that uses optimal transport theory to create context-dependent steering rather than global directions. The approach models representations as Gaussian mixture models and derives input-dependent steering maps, showing improved behavioral control over existing methods.

A Geometric Gaussian Mixture Representation of Plane Curves

Researchers introduce a Gaussian Mixture Model (GMM) framework that represents plane curves as probabilistic geometric primitives, encoding both tangential and normal uncertainty. This mathematical approach enables uncertainty-aware geometric modeling applicable to CAD, robotics, and digital twin applications.
