AWhat changed
Transferred bidirectional Transformer encoding and masked-item prediction to recommendation, then appended a mask at the history's end for next-item inference to address the training–prediction mismatch.
Scientific scope
Transferred bidirectional Transformer encoding and masked-item prediction to recommendation, then appended a mask at the history's end for next-item inference to address the training–prediction mismatch. Uses known BERT/Cloze components; it does not invent bidirectionality or masking. Historical right context is available during masked training, not future user actions at serving. Sequence length and training budget constrain results; no unconditional advantage over causal recommenders. Original v1's WOODSTOCK venue/DOI placeholders are not asserted as actual publication facts.
