Data annotation for sensor signals and system logs
I performed high-accuracy data annotation for sensor signals, including temperature and motion data, as part of embedded systems engineering tasks. The work required precise labeling of time-series sensor outputs and automated system logs to facilitate downstream algorithm training and validation. Annotation required careful calibration and validation to ensure engineering standards for data quality and consistency. • Labeled sensor output classes for supervised learning in control system prototypes. • Applied threshold-based and statistical techniques to classify anomalous vs. nominal signals. • Prepared annotated datasets for use in downstream embedded control projects. • Collaborated with technical team to ensure annotation consistency and reliability.
