- The portfolio reports a satellite change detector’s F1 score falling from 0.92 to 0.72 after a five-pixel image misalignment.
Field notes
The portfolio groups nine projects—eight marked complete and one release candidate—and offers Science and Apps filters. Its case studies name their validation routes: LensLab is checked against analytic images and an independent flux calculation, while Radar Track Lab uses public ADS-B tracks near Amsterdam. The latter reports 175 m position RMSE against 528 m for a nearest-neighbor baseline; code links appear alongside several projects.
