Medtronic

Machine Learning Engineer

Sep 2021 – Oct 2023 · 2 yrs 1 mo · Greater London · On-site

Collaborated with key members of Medtronic's digital surgery team, to build innovative models for surgical videos and biomedical images at scale.
1. Built an object tracking system for surgical instruments using ByteTracker algorithm and integrated with core machine learning service, this integration with yolo-x object detection helped improve detection accuracy by 5% .
2 .Migrated data pipelines to metaflow for large scale inference and feature extraction. Improved inference and feature extraction efficiency by 10 times the previously used python scripts.
4 .Developed Semantic segmentation model for anatomical structures that appear during cataract surgery with an IOU score of 91% . This segmentation model was then used for downstream analysis tasks of identifying regions of Interests in sections of videos.
