Sep 1, 2025Month: 2025-09. Key accomplishments centered on stabilizing the O2Physics NN v3 collision data processing path (input_dimensions=8). Major bug fixed: inconsistent handling of ft0cOccupancyInTimeRange, improving correctness and reliability of collision data processing. The change was implemented by duplicating a critical line of code to ensure consistent behavior across processing paths. The fix is linked to commit e4a38e5f5ebafa90754e2aa706eee68b6835a4b4 under the ticket [Common] Bug fix for NN version 3 development (#13128). Overall impact: higher stability and accuracy in NN v3 data processing, reducing downstream errors and enabling more reliable physics analyses. Technologies/skills demonstrated: debugging NN pipeline edge cases, Git version control and traceability, C++/Python code changes, and rigorous regression thinking.
