PROFILE

Vigh Sebastian

Sebastian-Robert Vigh contributed to the openvinotoolkit/openvino and aobolensk/openvino repositories by developing and refining model evaluation and testing tools in C++. He introduced new evaluation metrics such as mean Average Precision and L2 norm, implemented per-layer and per-output thresholding, and enhanced error handling to improve reliability. His work included refactoring metric helpers for maintainability and updating default thresholds to increase assessment accuracy. By addressing Coverity findings and integrating targeted testing capabilities, Sebastian improved code quality and testing flexibility. These efforts deepened the robustness of model QA pipelines, leveraging C++ development, machine learning, and OpenVINO for measurable evaluation improvements.

Dec 1, 2025

December 2025: Delivered a new object detection evaluation metric (mean Average Precision, mAP) and completed stability fixes in single-image test tools. The mAP metric enhances the accuracy assessment of detection models, aligning with accuracy_checker.py and enabling more reliable benchmarking. The stability fixes address Coverity findings to improve error handling and performance in the test tooling, increasing reliability of the OpenVINO testing pipeline. These efforts improve model QA, release confidence, and overall testing robustness, with direct impact on measurable evaluation quality and developer productivity.
