PROFILE
Majid Khoshrou
Contributed to the OpenSTEF/openstef repository by developing two new time-series features aimed at enhancing model input quality and capturing seasonal patterns. The work involved implementing cyclic time features using sine and cosine transforms for time of day, day of week, and month, delivered through modular Python feature generation code and accompanied by updated tests and datasets. Additionally, integrated an hourly terrestrial radiation dataset from CSV, creating a merge function that ensured timezone-aware processing and data integrity. Demonstrated skills in Python, Pandas, and time-series analysis, with a focus on robust data engineering, test-driven development, and improved ETL consistency throughout the project.

Dec 1, 2024December 2024 performance summary for OpenSTEF/openstef: Delivered two time-series feature enhancements to improve model inputs and capture seasonal patterns. Implemented cyclic time features using sine/cosine transforms for time components (time of day, day of week, month) with new feature generation modules, and updated tests/data to reflect the new features. Added daylight terrestrial radiation feature by integrating an hourly radiation CSV (May 2023 to May 2024) with an ingestion/merge function, and refactoring tests/data to accommodate timezones and data integrity. No major bugs fixed this month. Overall impact: expanded feature set, potential uplift in forecasting accuracy and robustness, improved data quality and ETL consistency. Technologies/skills demonstrated: Python, time-series feature engineering, modular design, data integration, CSV handling, timezone-aware processing, test-driven development.
