Abstract: Highlights•We introduce the task of Indoor Scene Classification to yield models useful for CSAI.•With partner law enforcement agents, we design new class splits on public scene datasets.•We evaluate different methods and hyperparameter tuning without accessing CSAI.•Self-supervision on indoor scenes improves their downstream performance.
