WebIn encoder-decoder frameworks, the cross-attention module dynamically selects relevant source-side information (key) given a target-side token (query) (Yang et al., 2024; Wang and Tu, 2024). ... cross-attention to adjacent tokens surrounding the source word with the maximum alignment probability. WebThe number of inputs must be consistent across all calls. The options are as follows: layer (decoder_sequence): no cross-attention will be built into the decoder block. This is useful when building a "decoder-only" transformer such as GPT-2. layer (decoder_sequence, encoder_sequence): cross-attention will be built into the decoder block.
