Notes on explainable AI, computer vision, and what deep learning models actually learn — mostly written around the DeepPVMapper case study.
What Does a Solar Panel Detector Actually See?

Explainable AI
Computer Vision
While developing DeepPVMapper, the recurring question was never how accurate the model was, but whether it was actually detecting solar panels. Answering that turned out to require a new way of explaining models — decomposing predictions into wavelet scales — and revealed that the model was, in fact, an excellent grid detector.
