Researchers have conducted an empirical audit of eight different input encoders for multi-channel signal transformers, evaluating their performance on synthetic and real-world datasets. The study found that most encoders performed similarly, with the standard per-channel linear projection being a practical default choice. Two encoders, the shared-scalar baseline and a channel-independent PatchTST-spirit baseline, performed significantly worse. AI
