    BODE-GEN

    An Exploratory Study of Bayesian Prompt Optimization for Test-Driven Code Generation with Large Language Models

    S. Tomar, A. Deshwal, Ethan Villalovoz, M. Fazzini, H. Cai, J.R. Doppa

    Studies Bayesian optimization for automated prompt search in test-driven LLM code generation, evaluated across HumanEval+ tasks and multiple code models.

    My contribution: I built the test-driven evaluation pipeline and ran reproducible experiments across 164 HumanEval+ tasks and three code models.

  2. Threatening-to-harmless ratings for V-shape, wedge, vertical-line, and horizontal-line robot formations

    IEEE/RSJ International Conference on Intelligent Robots and Systems, 2023

    Social Triangles

    Social Triangles and Aggressive Lines: Multi-Robot Formations Impact Navigation and Approach

    A. Bacula, Ethan Villalovoz, D. Flynn, A. Mehta, H. Knight

    Studies how multi-robot formation geometry shapes human navigation and approach behavior by comparing social triangles with aggressive lines.

    My contribution: I developed geometric motion primitives and Python tooling for the Pioneer 3DX formations evaluated in the study.
