Researchers have investigated the effectiveness of self-pretraining (SPT) for Transformer models in sequence classification tasks. Their work replicates and ablates previous findings, suggesting that SPT improves optimization by enabling models to learn useful attention patterns. Specifically, the study highlights that SPT helps models learn proximity interactions, transforming absolute positional encodings into attention scores that bias towards nearby elements. This approach proves more effective than standard supervised training in certain Transformer configurations, as label supervision can overlook beneficial attention directions that masked reconstruction can detect.
