Researchers have investigated how the architecture and training of deep learning models impact their representations, particularly in the context of experimental physics. Their study focused on time projection chamber (TPC) data, which can be represented as sparse tensors, and explored the reusability of these representations across different experiments and detector systems. By using probes on frozen encoders and comparing them with random-weight controls, the study aimed to differentiate the contributions of architecture versus training to downstream performance. The findings indicate that architectural choices significantly influence the structure of TPC embeddings, with some representations proving useful even before fine-tuning or across different experimental setups.
