Liu and Yao Zhao, Software Engineers, Google Research, HMS Cumberland, HMS Campbeltown, HMS Chatham and HMS Cornwall. (batch_size, num_heads, sequence_length, embed_size_per_head)) and 2 additional tensors of shape ( We evaluated our best PEGASUS model on 12 downstream summarization tasks spanning news, science, stories, instructions, emails, patents, and legislative bills. Hidden-states of the model at the output of each layer plus the optional initial embedding outputs. Summarization | NLP-progress deterministic: bool = True The PEGASUS Model with a language modeling head. Through the guide above, we hope that you are now able to adapt and adopt PEGASUS for your abstractive summarization tasks. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. And this library applies accel-brain-base to implement Encoder/Decoder based on LSTM improving the accuracy of summarization by Sequence-to-Sequence ( Seq2Seq) learning.
