PoliVEM: a Python-driven virtual element framework for computational solid mechanics
Paulo Akira F. Enabe, Rodrigo Provasi
This work presents PoliVEM, a software framework for the Virtual Element Method (VEM) in computational solid and structural mechanics. A C++17 computational core and a Python inter…
Anytime PAC-Bayes for Constrained Density-Ratio Networks under Covariate Shift
Paulo Akira F. Enabe, Rodrigo Provasi
A unified framework for learning under covariate shift is presented, in which a constrained density-ratio network approximates the Radon-Nikodym derivative and fe…
Profile-Then-Reason: Bounded Semantic Complexity for Tool-Augmented Language Agents
Paulo Akira F. Enabe
Large language model agents that use external tools are often implemented through reactive execution, in which reasoning is repeatedly recomputed after each observation, increasing…
An Investigation of Stabilization Scaling in Finite-Strain Virtual Element Methods for Hyperelasticity
Paulo Akira F. Enabe, Rodrigo Provasi
Low-order virtual element methods (VEM) compute a consistent finite-strain contribution through polynomial projections and rely on stabilization to control the unresolved modes in…
